SUMMARY:Fundamental Physics From Ground-Based Gamma-Rays Observations
DESCRIPTION:Crucial topics in fundamental physics\, such as the existence of new particles\, or violations of the Lorentz Invariance arising at the Planck scale\, can be effectively tackled in the cosmic environment\, by means of ground-based observations in the VHE gamma-ray band. This includes both Particle showers detectors\, such as LHAASO and Imaging Atmospheric Cherenkov Telescopes\, such as MAGIC\, H.E.S.S.\, or the forthcoming CTA and ASTRI Mini-Array. I will introduce\, without any objective of exhaustiveness\, how the existence of Axion-Like Particles (ALPs) or Lorentz Invariance Violations (LIV) have been investigated in the past\, or will be in the future\, by means of observations of some extragalactic sources such as blazars or GRBs. \nFecha: 19/12/2024 – 12:30Conferenciante: Dr. Giacomo BonnoliFiliación: Istituto Nazionale di Astrofisica\, Italy \n

SUMMARY:SO Colloquium: MOSAIC the high multiplex and multi-IFU spectrograph for the ELT
DESCRIPTION:MOSAIC is the planned multi-object spectrograph for the 39m Extremely Large Telescope (ELT). Conceived as a multi-purpose instrument\, it offers both high multiplex and multi-IFU capabilities at a range of intermediate to high spectral resolving powers in the visible and the near-infrared. In this talk I will showcase the key science cases that drive the top-level requirements and the adopted instrument architecture. With a planned first light in the early 2030s\, MOSAIC will enable unique spectroscopic surveys of the faintest sources\, from the oldest stars in the Galaxy and beyond\, to the first populations of galaxies that completed the reionisation of the Universe–while simultaneously opening up a wide discovery space and providing enormous synergies with upcoming multi-wavelength facilities (e.g.\, Euclid\, Rubin\, Roman\, SKA). \nFecha: 11/01/2024 – 12:30Conferenciante: Dr Ruben Sánchez-JanssenFiliación: STFC UK Astronomy Technology Centre The Royal Observatory Edinburgh \n

SUMMARY:UGR bureocrazy for dummies: PhDs fight back
DESCRIPTION:Every year we all wonder about the UGR bureaucracy: did we miss something? how could we have known in advance? Let’s face it\, it’s a mess. To try to help us all\, especially those who are just starting\, I would like to invite everyone interested to a seminar dedicated to understanding what the PhDs have to go through every year (paperwork related)\, where to find the proper information\, who to contact in case of doubt and how to go through the PhD paperwork a bit more smoothly. \nFecha: 16/01/2024 – 12:30Conferenciante: Teresa ToscanoFiliación: IAA – CSIC \n

SUMMARY:A Year Beyond the Horizon: Advancing Our Understanding of M87* with New EHT Observations.
DESCRIPTION:In this presentation\, we introduce the first follow-up Event Horizon Telescope (EHT) observations of M87*\, taken a year after the epoch-making first image. The enhanced imaging\, facilitated by additional antennas\, increased data rates\, and new imaging techniques\, not only provides greater detail but also enables us to study the dynamics of the black hole within a year. Due to the embargo\, specific results are not included in this abstract\, but will be disclosed in a press release scheduled for January 18 at 08:00 UT\, just hours before this talk\, enabling a detailed exploration of these findings and their contribution to our understanding of black hole physics. \nFecha: 18/01/2024 – 12:30Conferenciante: IAA-CSIC EHT groupFiliación: IAA – CSIC \n

SUMMARY:Stellar population studies in the J-PAS survey
DESCRIPTION:The Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS) is a large scale multi-filter survey that has started to observe 8500 deg² of the northern sky with 54 narrow-band filters in the optical range (3500-9600Å). In our Galaxy Evolution group at IAA-CSIC\, we aimed at developing and testing methodologies in order to perform stellar populations studies using this kind of data. More precisely\, I will introduce our SED-fitting codes and the potential of J-PAS to determine the integrated properties of the stellar content of galaxies up to redshift z~1 (including age\, metallicity\, stellar mass\, etc.)\, techniques for the determination of the stellar mass and luminosity functions of galaxies in this kind of surveys\, and how to constrain the stellar population properties of spatially resolved galaxies up to 2-3 half light radius only using the miniJPAS/J-PAS images by means of a tool that we are developing in our group (IFU-like studies). \nFecha: 25/01/2024 – 12:30Conferenciante: Dr. Luis Alberto Díaz GarcíaFiliación: IAA – CSIC \n

SUMMARY:The Transient High-Energy Sky and Early Universe Surveyor (THESEUS)
DESCRIPTION:The Transient HIgh-Energy Sky and Early Universe Surveyor (THESEUS) is a mission concept developed by a large European collaboration under study by ESA since 2018 and currently one of the three candidate M7 mission for a launch in mid ’30s. THESEUS aims at fully exploiting Gamma-Ray Bursts for investigating the early Universe and as key phenomena for multi-messenger astrophysics. By providing an unprecedented combination of X-/gamma-ray monitors\, on-board IR telescope and spacecraft autonomous fast slewing capabilities\, THESEUS would be a wonderful machines for the detection\, multi-wavelength characterization and redshift measurement of any kind of GRBs and many classes of X-ray transients\, including high-redshift GRBs for cosmology (pop-III stars\, cosmic reionization\, SFR and metallicity evolution up to the «cosmic dawn») and electromagnetic counterparts to sources of gravitational waves\, especially short GRBs\, possible soft X-ray emission and KN emission from NS-NS / NS-BH mergers. THESEUS would thus provide an ideal synergy with the very large astronomical facilities of the future working in the e.m. (e.g.\, ELT\, CTA\, SKA\, Athena) and multi-messenger (e.g.\, Einstein Telescope\, Cosmic Explorer\, km3NET). \nFecha: 08/02/2024 – 12:30Conferenciante: Dr. Lorenzo AmatiFiliación: INAF – OAS Bologna\, Italy \n

SUMMARY:Recent Progress in Understanding Solar Flare Magnetism using Data-Driven Simulations and Statistical Analysis of Vector Magnetic Fields
DESCRIPTION:Continuous vector magnetic-field measurements by the Helioseismic and Magnetic Imager (HMI) onboard the Solar Dynamics Observatory (SDO) allowed us to run data-driven simulations of solar eruptions and perform statistical studies of magnetic-fields for many flares. In this talk I will review new aspects of flare magnetism discovered using SDO data\, including progress in data-driven simulations and statistical studies of magnetic-reconnection fluxes\, their rates and magnetic-field changes during flares. I will summarize how these results\, along with statistical studies of eruptive and confined flares\, have improved our understanding of flares and the flare/CME feedback relationship. \nFecha: 19/03/2024 – 12:30Conferenciante: Dr. María KazachenkoFiliación: University of Colorado\, USA \n

SUMMARY:Single-photon gig in Betelgeuse’s occultation
DESCRIPTION:In the realm of astronomical exploration\, cutting-edge technologies are indispensable. Single-Photon Avalanche Diode (SPAD) sensors offer unparalleled precision\, enabling the detection of individual photons with remarkable timing resolution. However\, the current use of single-pixel SPAD devices poses limitations on spatially-resolved imaging in astronomy. Enter two-dimensional SPAD detectors\, revolutionizing observation capabilities and enabling the study of rapid cosmic phenomena. \nThis talk explores the transformative potential of two-dimensional SPAD detectors in observational astronomy. Focusing on recent advancements\, we discuss their ability to capture rapid fluctuations in celestial events\, offering insights into phenomena previously beyond reach. Leveraging these innovations\, we present our results on the occultation of Betelgeuse by asteroid (319) Leona\, showcasing the unprecedented temporal resolution achieved with SPAD technology. \nFecha: 02/04/2024 – 12:30Conferenciante: Dr. Francisco PradaFiliación: Instituto de Astrofísica de Andalucía – CSIC\, Granada \, Spain \n

SUMMARY:The Earthbound Fate of Meteor Phenomena
DESCRIPTION:Understanding meteor phenomena is essential for promptly and effectively recovering meteorites\, predicting meteor showers\, studying atmospheric properties\, and assessing the threat posed by space objects to both in-orbit and ground-based infrastructure. By observing and interpreting meteor phenomena\, we can predict impact consequences and efficiently locate and identify surviving meteorite fragments on the ground. Through dimensional analysis\, we have developed a physical model that reduces the number of unknowns without requiring any of them to be preset. This model accurately estimates changes in mass\, velocity\, and luminosity\, while also predicting the duration of the phenomenon. The model has yielded success in studying various meteor events\, facilitating the recovery of meteorites such as Annama and Ozerki\, and more recently\, quantifying meteor phenomena in the atmosphere of Venus. In addition to describing the model\, its application is demonstrated using a diverse range of observational data\, including larger-scale impactors such as Chelyabinsk\, Canyon diablo\, Sikhote-Alin\, and the Tunguska event. \nFecha: 04/04/2024 – 12:30Conferenciante: Dr. Maria GritsevichFiliación: University of Helsinki\, Finland \n

SUMMARY:Laboratory Research on the Atmospheric Impact of Spacecraft Re-entry Debris: Perspectives and Future Challenges
DESCRIPTION:The rapid growth of space debris\, especially in Low Earth Orbit (LEO)\, poses a rising risk to both space operations and Earth’s atmosphere.  Debris fragments\, even minuscule in size\, can cause significant damage due to their high orbital speeds. To mitigate risks\, controlled re-entry of debris is common practice\, but this introduces a new concern: the increasing mass of human-made materials injected into the atmosphere. As satellites and rocket bodies disintegrate\, they release substantial quantities of metals\, altering the composition of the stratospheric aerosol. The effects of these new materials within the stratospheric aerosol are still uncertain. It’s likely that metals from re-entering spacecraft mix with and condense onto meteoric smoke particles (MSP) descending from higher altitudes. Further coagulation likely occurs as these particles continue their descent into the stratosphere. Besides\, aluminium and other novel elements found in stratospheric aerosols might influence the formation (nucleation) of ice or nitric acid trihydrate (NAT). This carries significance because even small amounts of these new ice nuclei could drastically alter the development of polar stratospheric clouds (PSC). Prior research supports this idea\, showing that substances similar to meteoric inclusions within sulfuric acid can trigger ice formation. Furthermore\, studies indicate that metal cations have the ability to induce efflorescence within aerosol particles\, critically impacting radiative forcing. In this presentation\, I’ll discuss the gas-phase chemistry of these anthropogenic metals\, offering insights into how they might react and alter the stratospheric aerosol. Finally\, by identifying knowledge gaps and outlining the necessary research\, we can work towards developing a comprehensive understanding of this emerging environmental issue. \nFecha: 09/04/2024 – 12:30Conferenciante: Dr. Antonio OcañaFiliación: IAA – CSIC \n

SUMMARY:LP791-18d as a case study for outgassing rocky exoplanets
DESCRIPTION:Over the past three decades\, the discovery of over five thousand exoplanets has opened avenues for atmospheric characterization\, now feasible for a select subset through spectroscopic observations paired with Bayesian inference techniques. These exoplanetary atmospheres serve as crucial windows into planetary formation and evolutionary histories. Achieving accurate interpretations demands a comprehensive approach\, advancing theory and modeling to understand the continuous interplay between exoplanetary atmospheres and their surrounding environments—both lower and upper boundaries. This project focuses on rocky exoplanets situated near their host stars\, often exhibiting states of magma oceans or heightened volcanic activity due to proximity and tidal forces from neighboring planets. These unique candidates offer enhanced opportunities for observing the ongoing production of secondary atmospheres through outgassing processes. We present a holistic modeling framework for understanding interior-atmosphere interactions and predict the atmospheric footprint of the planet’s interior based on its oxidation state. Moreover\, we assess the detectability using the James Webb Space Telescope (JWST) and propose a spectral index capable of inferring the oxidation state of a planet’s interior. \nFecha: 11/04/2024 – 12:30Conferenciante: Dr. Leonardos GkouvelisFiliación: Ludwig-Maximilians-University of Munich\, Germany \n

SUMMARY:Astronomy with Neutrino Telescopes
DESCRIPTION:In recent decades\, high-energy neutrinos of astrophysical origin have become integral members of the multi-messenger astronomy community. Neutrino telescopes have a very particular way to observe the sky\, with characteristics different from any other telescope. They are capable of continuously observing the entire sky simultaneously\, yet they also necessitate the accumulation of a significant amount of statistical data. IceCube reported the first evidence of high-energy cosmic neutrinos in 2013\, with very interesting excesses in the later years from TXS 0506+056\, NGC 1068 and also the Galactic plane. The discovery of new sources holds promise during the current decade\, as an increasing number of detectors yield more statistical data with even better angular resolutions. \nIn this talk\, I will discuss the distinctive features of neutrino telescopes and provide an overview of the current state of neutrino astronomy. I will explore various cosmic neutrino search strategies\, ranging from diffuse flux investigations to gravitational wave follow-ups\, with a focus on Mediterranean-based projects such as ANTARES and KM3NeT\, in conjunction with IceCube. \nFecha: 15/04/2024 – 12:30Conferenciante: Agustín Sánchez LosaFiliación: Instituto de Física Corpuscular-CSIC\, Valencia\, Spain \n

SUMMARY:Artificial Intelligence in Service of Galaxy Evolution Research: A Personal Journey
DESCRIPTION:In this seminar\, I will present my personal exploration of the application of artificial intelligence in the study of galaxy evolution. Since the early 2010s\, the fields of machine learning and deep learning have undergone unprecedented development\, marked by enhancements in algorithms and hardware advancements. This progress has significantly influenced various scientific domains. Concurrently\, the increasing volume and complexity of data produced by modern and upcoming astronomical surveys such as J-PAS\, DESI\, LSST\, and SKA necessitate the adoption of new analytical tools capable of processing and interpreting this data faster and effectively. \nInitially\, the first applications of AI in astronomy made used of multilayer perceptrons to address challenges such as estimating the photometric redshift of galaxies. Today\, most AI applications in astronomy primarily employ supervised learning with sophisticated neural networks like CNNs\, RNNs\, and LSTMs. These are focused on estimating physical properties or performing classifications of astronomical objects. However\, a shift towards a new paradigm in computer science emphasizes the use of generative AI models trained via unsupervised learning methods. Prominent examples include tools like ChatGPT\, Stable Diffusion\, Sora\, Udio\, and others. This transition is now making inroads into the field of astronomy\, offering promising avenues for the development of what is being called foundational models. These models have the potential to integrate data across multiple surveys and wavelengths\, creating a more robust framework for interpreting theory and observations. \nFecha: 25/04/2024 – 12:30Conferenciante: Dr. Ginés Martínez SolaecheFiliación: IAA-CSIC\, Granada\, Spain \n

SUMMARY:The art of astrophysical measurements: An elementary lecture on photon counting and S/N
DESCRIPTION:Have you ever dared to understand how many photons are detected by your camera when you are pointing the telescope to the sky? Is the action of the spectrograph fully understood when analyzing those photons? Do typical image formation rules hold when studying the polarization of light? All these are a few examples of questions addressed by researchers when designing instruments\, which are later constrained by technological capabilities. This talk will summarize them with the aim of triggering basic curiosity of scientists to get an insight on the means at their disposal to investigate the Universe. \nFecha: 30/04/2024 – 12:30Conferenciante: Dr. José Carlos del Toro IniestaFiliación: IAA-CSIC\, Granada\, Spain \n

SUMMARY:Journey into the Galactic Heart: Illuminating the Enigma of the Nuclear Star Cluster and the Nuclear Stellar Disc
DESCRIPTION:The innermost regions of most galaxies are characterised by the presence of extremely dense nuclear star clusters\, which sometimes appear together with larger stellar structures known as nuclear stellar discs. Understanding the relation between nuclear star clusters and nuclear stellar discs is challenging due to the large distance towards other galaxies which limits their analysis to integrated light. In this context\, the Milky Way’s centre\, which hosts both structures\, appears as a unique template to understand their relation and formation scenario. Using photometric\, metallicity and kinematic catalogues\, we analysed the relation between these two Galactic centre components and study their stellar populations. We detect kinematic and metallicity gradients along the line of sight\, suggesting a smooth transition between the nuclear stellar disc and cluster. Our results suggest that these two Galactic centre components might be part of the same structure\, with the Milky Way’s nuclear stellar disc being the grown edge of the nuclear star cluster. \nFecha: 07/05/2024 – 12:30Conferenciante: Francisco Nogueras LaraFiliación: ESO\, Garching\, Germany \n

SUMMARY:New possibilities for atmospheric analysis with Monte Carlo
DESCRIPTION:In recent years\, significant advancements have been made in scientific computing utilizing the Monte Carlo method\, particularly at the intersection of two key communities: the heat transfer community and the computer graphics community. The first breakthrough is that the computation time required to solve radiative transfer becomes invariant\, whether the ground is described by a single building or thousands of them\, whether the 3D clouds are poorly resolved or refined. We recently published in the journal PNAS a climate-analysis-oriented application showing this computation time invariance\, extending to the spectral\, spatial\, and temporal domains. The second breakthrough of the paper lies in the nonlinear coupling of radiative transfer and gas spectroscopy\, allowing estimation of unbiased line-by-line radiative quantities\, even when considering scattering. This opens up new analysis prospects\, initially applied to Earth and now expanding to Titan. \nFecha: 14/05/2024 – 12:30Conferenciante: Dr. Yannis Inouk Nyffenegger PéréFiliación: IAA – CSIC \n

SUMMARY:A complex network perspective on Delta Scuti stars
DESCRIPTION:We apply horizontal visibility graphs (HVG) to study the complex network behavior for the delta Sct stars’ light curves observed by TESS. The delta Sct stars are pulsating stars with spectral types A0-F5 and intermediate masses between low-mass stars (≤ 1 Msun) and high-mass stars (≥ 2 Msun). They pulsate in low-order pressure modes and have dominant pulsation frequencies in the 5-80 d−1 range. The high amplitude delta Sct stars (called HADS)\, are classified in population I of delta Sct stars with V band amplitude ≥ 0.3 mag and low-amplitude delta Sct stars (called LADS) pulsate in several modes with V band amplitudes ≤ 0.1 mag. The lower clustering for high amplitude delta Sct than low amplitude delta Sct indicates a more straightforward light curve (containing one or two independent modes) than a more complex light curve. The average shortest path length of the HVG network of delta Sct light curves is a linear function of the network sizes (logarithm)\, indicating the small-world and non-random properties. By considering the degree distributions of stellar networks\, both lognormal and power-law behaviors of nodes’ degrees are likely not to be rejected\, and deviation from the analytical expression of uncorrelated random series is evidence for non-random processes. \nFecha: 06/06/2024 – 12:30Conferenciante: Dr. Elham ZiaaliFiliación: Instituto de Astrofísica de Andalucía – CSIC \n

SUMMARY:Intersexionality\, a key work for diversity?
DESCRIPTION:Since we are children we have been taught what we are and we learn how to fit into a set of infinite boxes. Each of these boxes defines us and\, at the same time\, can be used to discriminate against us\, in life and at work. Diversity exists and it could be an advantage for our society. As scientists we should understand how to take care of diversity and use it to improve our work and life quality. One of the main problems in the past has been that humankind tried to build a rank of «important differences» which led to discrimination\, ending up discriminating among differences. In the last decade\, gender studies’ idea of intersectionality has become popular and this has affected the way by which many of us are now looking at EDI activities. \nIn this talk I will provide some background on EDI\, then\, I will discuss success and failures of the EDI activities I have been part of to stimulate a discussion about the best way to improve our working environment. \nFecha: 25/06/2024 – 11:00Conferenciante: Dr. Eleonora FiorellinoFiliación: INAF – Osservatorio Astronomico Capodimonte Napoli\, Italy \n

SUMMARY:Multiple components in the protostellar system HH 212: Infalling envelope\, nested shell\, MHD disk winds\, and free wind gas
DESCRIPTION:I will present the Atacama Large Millimeter/submillimeter Array Band 7 observations at ~24 au spatial resolution of the CO (J=3-2) and H13CO molecular lines emission of the protostellar system HH 212 and compare them with the emission of the SiO (J=8-7) and SO (J=8-7) molecular lines. From the large to small scale\, previous observations have detected the infalling envelope\, CO outflow shell\, SO disk wind\, SiO expanding shell and jet in the system. By comparing these components\, we find that the CO molecular line traces four different regions of the system: (1) the external nested shell\, (2) the wide-angle magnetohydrodynamic (MHD) disk winds\, (3) free wind gas inside the expanding SiO shell\, and (4) the protostellar jet. The origin of the CO external nested shell could be associated with the entrained material of the envelope either by the jet-driven bow shocks or by an outflowing gas launched from the central star or the accretion disk. As found in a previous SO study\, the wide-angle MHD disk winds are launched directly from the accretion disk from a region of Rlaunch~4-8 au  and with a magnetic lever arm  3.5-4.5. The CO free wind gas inside the expanding SiO shell could be associated with material ejected directly from the accretion disk. \nFecha: 27/06/2024 – 12:30Conferenciante: Dr. Alejandro López-VázquezFiliación: Academia Sinica\, Institute of Astronomy and Astrophysics\, Taipei\, Taiwan \n

SUMMARY:Dust in protoplanetary disks\, (still) that great unknown
DESCRIPTION:Planetary systems are a side effect in the formation of a star. Planets are believed to be just simply the last remaining of dusty circumstellar disks which is formed around the protostar at very early stages. Thus\, understanding how planets are formed requires to understand how dust evolve in these disks. It is less than ten years that we have the possibility of mapping the dust distribution in protoplanetary disks with great detail with powerful radio interferometers such as the VLA and ALMA. We were highly surprised by the first images showing a rich diversity of substructures in the disk distribution\, consequence or initial stages of forming planets. We have already mapped hundreds of disks in different regions and we are now proposing different paths in the evolution of disks that will end in very different planetary systems. We are stating to understand the importance of ice lines in the formation of planetesimals. But\, probably the most surprising result is the realization that we ignorance about the internal structure of the dust grains prevent us of obtaining basic properties of the dust such as their mass or size. In this talk\, I will summarize how we arrived to this point and how we can unlock this situation. \nFecha: 11/07/2024 – 12:30Conferenciante: Carlos Carrasco GonzálezFiliación: UNAM\, Mexico \n

SUMMARY:The QUIJOTE experiment: status\, latest results and future plans
DESCRIPTION:Iwill review the current status and future plans of the QUIJOTE (Q-U-I JOint TEnerife) experiment\, a project with the aim of characterising the polarisation of the Cosmic Microwave Background\, and other galactic or extragalactic physical processes that emit in microwaves in the frequency range 10-42GHz\, and at large angular scales (1 degree resolution). The project has two radio telescopes (2.25m primary aperture) and three instruments\, MFI (10-20GHz)\, TFGI (30-40GHz) and MFI2 (10-20GHz). \nIn relation to MFI\, which observed the sky from 2012 to 2018 at 11\, 13\, 17 and 19GHz\, I will review the scientific results associated with the characterization of the polarized foreground emissions in the northern sky\, with special emphasis on the synchrotron and AME components. These results have been presented in a series of papers between 2023 and 2024. \nI will also present status of the other two instruments\, TFGI (30-40GHz) and MFI2 (10-20GHz). TFGI started operations in 2021 with 7 detectors\, and will resume observations with 19 detectors this summer. Preliminary results from the period 2021-2022 will be discussed. MFI2 has started the commissioning phase in March 2024. I will present the first light results and commissioning data. Finally\, I will describe the plans for developing a 90GHz camera for QUIJOTE. \nFecha: 23/07/2024 – 12:30Conferenciante: Dr. José Alberto Rubiño MartínFiliación: Instituto de Astrofísica de Canarias\, Spain

SUMMARY:Constraining the Meteoroid Flux in the inner solar system
DESCRIPTION:​The inner solar system is populated by Interplanetary Dust Particles (IDPs) released from cometary trails and collisions between asteroids. Planetary bodies and satellites therefore encounter a cloud of IDPs along their orbits\, giving rise to a permanent bombardment on their respective atmospheres or surfaces. Constraining the magnitude of the mass influx of IDPs onto a solar system body is crucial for understanding the effects in their atmospheres and on their surfaces. \nFor planetary bodies with atmospheres\, collisions with air molecules lead to the thermal ablation of IDPs above their melting temperature and\, therefore\, their constituent elements evaporate and produce layers of free neutral and ionized atoms\, being Mg\, Fe\, Si\, and Na the major metallic species. Metallic layers in the Earth’s atmosphere have been widely studied for decades using ground-based lidar and space-based optical spectroscopy. In the case of Mars\, the Mars Atmosphere and Volatile Evolution (MAVEN) Imaging Ultraviolet Spectrograph (IUVS) reported the first detection of a persistent Mg+ layer in Mars’ atmosphere peaking around 90 km. \nIn this talk\, firstly I will review the most relevant modelling results for the meteoroid mass influx at the Earth\, Mars\, and Venus. Second\, I will discuss the results of the most recent state-of-the-art models able to provide a comprehensive description of the meteoroid impacts accounting for the temporal\, latitudinal\, and seasonal distributions of the main meteoroid populations in the inner solar system. \nFecha: 24/09/2024 – 12:30Conferenciante: Dr. Juan Diego Carrillo SánchezFiliación: NASA Goddard\, US

SUMMARY:The stellar distribution in ultra-faint dwarf galaxies suggests deviations from the collisionless cold dark matter paradigm
DESCRIPTION:Unraveling the nature of dark matter (DM) stands as a primary objective in modern physics. I will present evidence suggesting deviations from the collisionless Cold DM (CDM) paradigm. In the standard cosmological model the dark matter (DM) particles are collisionless and\, because of this very nature\, they develop halos with the characteristic central cusp known as NFW profile. Real galaxies do not show NFW profiles but\, rather\, have a DM mass distribution with a central plateau or core\, characteristic of self-gravitating systems in thermodynamic equilibrium. Within the standard model\, the collisionless DM reaches equilibrium through baryon-driven processes able to transform the overall potential from cusp to core. Such mechanism becomes inoperative for galaxies with few stars (stellar mass <1e6 Msun)\, thus\, finding cores in these low-mass galaxies would indicate that the DM is not collisionless\, reflecting the much sought-after and currently unknown true nature of the DM (whether it is fuzzy\, self-interacting\, warm\, or else). Measuring the DM distribution in tiny galaxies through traditional dynamical indicators is impossible\, but we have developed a tool to constrain the distribution of DM from the stellar photometry alone. We have used the tool to analyze the stellar cores observed in 6 Ultra Faint Dwarf (UFD) galaxies with stellar masses between 1e3 and 1e4 Msun. They do not live in a NFW potential. Other conceivable explanations for the observed cores are disfavored by simulations and/or observations. Thus\, the evidence suggests that collisions among DM particles or other alternatives to CDM are likely shaping these galaxies. \nFecha: 26/09/2024 – 11:00Conferenciante: Dr. Jorge Sánchez AlmeidaFiliación: Instituto de Astrofísica de Canarias\, España

SUMMARY:High-Resolution Study of Blazar TXS 2013+370 and BEAM: A Space Technology and Research Student Team
DESCRIPTION:The talk will focus on two key areas. Part one will present the high-resolution imaging of Blazar TXS 2013+370\, a study conducted as part of an M.Sc. thesis. This research aims to resolve the inner jet structure of the compact radio source TXS 2013+370 in total intensity and polarization. This analysis utilizes VLBA data combined with Effelsberg observations at frequencies of 22 GHz\, 43 GHz\, and 86 GHz. Part two will highlight BEAM\, a student space association at the  Aristotle University of Thessaloniki in Greece. This section will  cover various projects undertaken by the team during student  competitions organized by ESA and other European space organizations.  It will also discuss the latest project\, ASTRO\, which aims to design  and construct a 5-m radiotelescope at the university. \nFecha: 30/09/2024 – 13:00Conferenciante: Giorgos MichailidisFiliación: Aristotle University of Thessaloniki\, Greece

SUMMARY:Uncovering the magnetized path of massive star formation
DESCRIPTION:Both observational and theoretical studies suggest that the magnetic field plays an important role in the process of massive star and cluster formation. However\, many open questions still remain\, including the exact role of B-field at the different scales (from cloud to disk scales) and its importance compared to turbulence\, feedback and self-gravity. Multi-scale studies of the morphology and strength of the magnetic field are thus crucial to properly unveil the role of the magnetic field in the formation of high-mass stars. In this talk\, I will mainly focus on the multi-scale study of the magnetic field toward the high-mass star-forming region G31.41+0.31 carried out with both single-dish and interferometric observations of polarized dust emission. G31.41+0.31 is one of the most studied objects in polarized emission and the first high-mass star-forming core to show an hourglass-shaped magnetic field morphology. Finally\, I will also present three on-going observational campaigns that will allow us to further constrain the role of the magnetic field in massive star formation and to construct a multi-scale magnetized path of massive star formation. \nFecha: 10/10/2024 – 12:30Conferenciante: Dr. Chi Yan (Paul) LawFiliación: INAF – Osservatorio Astrofisico di Arcetri\, Italy

SUMMARY:Using CHEOPS to confirm small transiting exoplanets orbiting bright stars
DESCRIPTION:Exoplanets which transit their host stars are unique in allowing detailed characterisation of planetary radius\, mass and atmospheric properties. NASA’s TESS mission\, which has so far observed 97% of the sky with precise photometry\, is especially adept at detecting small transiting planets orbiting the brightest & closest stars. It is these for which the most precise bulk characterisation\, for example of the planetary masses via the radial velocity (RV) technique\, and atmospheric characterisation via transmission spectroscopy with JWST observations. However\, the limited precision and noncontinuous observing strategy of TESS means it is unable to find the smallest or longest period planets. ESA’s CHEOPS mission is a 30cm space telescope launched to near earth orbit in 2019 and capable of precise photometry of bright stars. I will present multiple avenues whereby we have used CHEOPS observations to confirm new transiting exoplanets. This includes confirming low-amplitude TESS candidate planets in the HIP 29442 system\, serendipitous detection of additional planets in the nu2 Lupi\, HD 108236 & LHS 1903 systems\, and RV-assisted transit detections in the TOI-561 system. The most productive approach has been to target candidates showing two non-continuous TESS transits. This has lead to around 20 newly detected sub-Neptunes on long periods\, including in multi-planet systems such as TOI-2076\, HIP 9618\, and the resonant 6-planet system HD110067. \nFecha: 31/10/2024 – 12:30Conferenciante: Dr. Hugh OsbornFiliación: Physics Institute\, University of Bern & Institute for Particle & Astrophysics\, ETH Zurich
