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:Who Is Afraid of the Dark (Energy)?
DESCRIPTION:Cosmic acceleration dominates the behavior of the recent universe\, with some fundamentally new physics at its heart. Recent data gives a tantalizing suggestion that the dark energy behind it is more complicated than a cosmological constant. Nevertheless\, we do know a lot about how to describe dark energy behavior. Data within the next year has great promise to give further insight\, and exciting new instruments are being planned. \nFecha: 27/09/2024 – 12:30Conferenciante: Dr. Eric LinderFiliación: Lawrence Berkeley National Laboratory\, USA.

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
