SUMMARY:A Minion in PANIC arrives to Calar Alto Observatory
DESCRIPTION:Calar Alto has a new tenant: PANIC\, the PAnoramic Near-Infrared Camera for Calar Alto. PANIC is a project jointly developed by the MPIA in Heidelberg\, Germany\, and the IAA in Granada\, Spain\, for the Calar Alto Observatory (CAHA; Almería\, Spain). \nThis instrument can work with the 2.2 m and 3.5 m telescopes. Its original detector has been recently replaced by a monolithic HAWAII-4RG\, therefore the instrument covers now a field of view of 26×26 arcmin and 13×13 arcmin at each telescope\, respectively\, with a sampling of 4096 × 4096 pixels without gaps. It is designed for the spectral bands from Z to Ks\, but can also be equipped with narrow band filters\, such as H2\, Br-gamma. It is the first 4K infrared camera for the European sky! \nPANIC had its first light at the 2.2m telescope in November 2014 and was accepted by CAHA in 2015 under the statement that all parties (CAHA\, MPIA and IAA) agreed that the array of four Hawaii-2RG detectors should be replaced as soon as possible. The replacement was successful\, the commissioning fruitful\, and the instrument is upgraded and ready to be used by the scientific community! PANIC can be booked for observation at the 2.2 m telescope starting next semester\, the call for proposals is already open and the deadline is on 10th April 2025. \nIn this talk we present the work done to upgrade the instrument with this new detector\, the instrument performance and the high level software. This software has been developed for the planning of the observations (Observation Tool)\, for the interactive analysis of images during the observations (Quicklook)\, and for the final data reduction (PAPI\, PANIC Pipeline). \nCurious about the Minion? Come to our talk! \nFecha: 01/04/2025 – 12:30Conferenciante: Ana Guijarro\, Vianak Naranjo\, Antonio J. García\, José M. Ibáñez and Sara MuñozFiliación: MPIA\, CAHA and IAA-CSIC\, Germany/Spain \n

SUMMARY:Phase curve fitting in the context of large-scale photometric surveys
DESCRIPTION:The shallow potential wells of low-mass galaxies\, commonly known as dwarf galaxies\, make them highly susceptible to environmental effects\, often leading to the complete cessation of star formation. But is quenching solely driven by external forces in harsh environments\, or can dwarf galaxies also self-quench through mechanisms like strong stellar winds or supernova feedback\, independent of external influences? In this contribution\, I present our latest findings on a sample of isolated and quenched dwarf galaxies in the sparse environments of the cosmic web\, including voids and filaments. With no neighbors within a 1 Mpc radius\, these galaxies reside in environments where traditional quenching mechanisms—such as ram pressure stripping and tidal interactions—are negligible. Intriguingly\, some of these galaxies ceased forming stars 7 to 8 Gyr ago\, exhibiting star formation histories akin to dwarf galaxies in the dense cores of massive clusters like Virgo and Fornax. The existence of such galaxies in vastly different environments challenges conventional quenching paradigms and highlights the need to explore alternative mechanisms\, including internal feedback processes and distinct formation pathways. Understanding these processes alongside environmental effects is crucial for developing a more complete picture of star formation cessation in dwarf galaxies. \nFecha: 03/04/2025 – 12:30Conferenciante: Dr. Milagros ColazoFiliación: Astronomical Observatory Institute\, Faculty of Physics and Astronomy\, Adam Mickiewicz University \n

SUMMARY:Synthetic ngVLA Observations of Ionized Gas in Massive Protostars and Future Prospects for Protoplanetary Disk Studies with ngVLA and SKA
DESCRIPTION:The study of protoplanetary disks is essential for understanding stellar evolution and the origins of planets. However\, these systems present significant observational challenges due to their small angular size\, low surface brightness\, and complex structure. Radio interferometry provides a unique advantage by observing dust and gas at wavelengths that penetrate the dense regions where the protoplanetary disk forms. The upcoming Next Generation Very Large Array (ngVLA) will transform protoplanetary disk studies with its unprecedented angular resolution and sensitivity in the millimeter and centimeter bands. These capabilities will allow high-fidelity imaging of disk substructures\, planet-disk interactions\, and dust evolution\, offering critical insights into the processes shaping planetary systems. The Square Kilometre Array (SKA) will complement these efforts by detecting cold molecular gas\, magnetic fields\, and ionized material\, providing additional constraints on disk dynamics and chemistry. Together\, these facilities will enable a multi-scale\, multi-phase perspective on planet-forming environments. \nA major challenge associated with these observatories is the immense volume of data they will generate and the necessitating advanced deconvolution and imaging techniques to reconstruct high-fidelity images. In this talk\, I will present results from simulated ngVLA observations of ultracompact HII regions (Jáquez-Domínguez et al. 2025) and my current work on protoplanetary disks\, where I am testing the capabilities and optimal configurations of ngVLA and SKA to maximize their scientific performance. By combining state-of-the-art radiative transfer models with next-generation imaging techniques\, we aim to refine strategies for future high-resolution disk studies. These efforts will be crucial for unlocking the full potential of ngVLA and its synergy with SKA and ALMA\, paving the way for transformative discoveries in planet formation. \nFecha: 08/04/2025 – 12:30Conferenciante: Dr. Miguel JáquezFiliación: IRyA (UNAM)\, México \n

SUMMARY:Impacts of Cosmic Dust in the Atmospheres of Mars and Venus
DESCRIPTION:Cosmic dust particles are produced from the sublimation of comets and by collisions between asteroids. Because the particles enter a planetary atmosphere at hypersonic velocities\, collisional heating with air molecules causes a fraction of them to melt\, leading to vaporization of their metallic constituents. The injection of these elements causes a wide variety of atmospheric phenomena in the terrestrial atmosphere\, including the formation of global layers of metal atoms between 80 and 105 km; airglow emissions; layers of metallic ions which affect radio communications; and the production of meteoric smoke particles which enable the nucleation of mesospheric ice clouds and the freezing of polar stratospheric clouds. Certain metal atoms can be observed very precisely by ground-based lidar and from satellites\, providing an excellent tracer of dynamics and chemistry at the edge of geospace. \nThe input rate of cosmic dust to the Earth’s atmosphere has been very uncertain. A new estimate of around 28 tonnes per day globally will be discussed; this was obtained using an astronomical dust model to provide the size and velocity distributions of dust in the inner solar system\, combined with the Leeds Chemical Ablation Model (CABMOD) to determine the rate of injection of metals into the atmosphere. CABMOD is itself benchmarked using a novel Meteoric Ablation Simulator to measure the evaporation rates of metals from meteoritic particles that are flash heated\, simulating atmospheric entry. The dust inputs into the atmospheres of Mars (2 t d-1) and Venus (31 t d-1) can now be constrained using the terrestrial input. \nThe chemistry of the four most abundant meteoric ablation elements – Mg\, Fe\, Si and Na – has been constructed from laboratory measurements and theoretical calculations of the rate coefficients for over 120 individual reactions involving neutral and ionized species. This chemistry\, together with the relevant metal injection rates as a function of height\, location and time\, has been inserted into the Planetary Climate Models for Mars and Venus developed in Paris (LMD) and Granada (IAA). For Mars\, model simulations generally compare well against observations of metallic ions made by instruments (IUVS and NGIMS) on NASA’s MAVEN spacecraft. In particular\, the diurnal\, latitudinal and seasonal variations of the Mg+ layer centred around 95 km are captured well. However\, there are several interesting differences higher in the ionosphere that are currently unexplained. \nIn the case of Venus\, metallic species have never been observed. However\, the PCM-Na model predicts that the atomic Na layer around 110 km should be observable at the dawn terminator by a terrestrial telescope-spectrometer. Metallic carbonate species are also predicted to act as ice nuclei\, forming transient CO2-ice clouds above 110 km. CO2-ice clouds may also form in the upper haze layer between 80 and 90 km\, in cold pockets produced by gravity waves. The sedimentation and subsequent evaporation of these large particles would lead to the downward transport of various atmospheric constituents. Finally\, a strong candidate for the mystery absorber in the Venusian clouds is iron trichloride (FeCl3)\, produced by the extra-terrestrial input of Fe. In contrast\, the SO dimer OSSO\, which has been favoured in the past to explain the absorber\, should make a negligible contribution.   \nFecha: 10/04/2025 – 12:30Conferenciante: Dr. John PlaneFiliación: School of Chemistry\, University of Leeds\, Leeds\, UK \n
