ESP2024 – PLATO PLANETARY SYSTEMS: Formation to Observed architectures

Department of Physics and Astronomy "Ettore Majorana" (DFA) of the Catania University Via Santa Sofia 64, Catania, Italia

PLATO is the 3rd mission of class M in the ESA Cosmic Vision program. Its main goal is detecting terrestrial planets in the habitable zone of solar type stars. With its huge FOV, most of the PLATO targets are bright stars that will be monitored with high cadence (25 s) for at least 2-3 years during the long duration observing program, while contemporary a number of very bright stars in the sample will be observed with 2.5 s cadence. The collected data, photometry from space and high resolution spectroscopy from the ground, will provide accurate planetary structures as well as architectures and evolutionary stage - via asteroseismic analysis - of a large number of planetary systems. PLATO is planned for a launch in Dec 2026.

Resilience of Eukaryotic Life in Mars-Like Simulated Conditions

Sede A. Riccò Via Santa Sofia 78, Catania

Constraining the survivability of different organisms to space-like conditions is of great interest
for Astrobiology. Extreme conditions can lead to alteration in the metabolic pathways of biological
systems. To identify organisms of interest for future astrobiological studies, it is necessary to
investigate their physiological parameters to understand the mechanisms involved in metabolic
rearrangement.

Neural Networs: new models for recovering the Cosmic Microwave Background

Sede A. Riccò Via Santa Sofia 78, Catania

The Cosmic Microwave Background, the relic emission from the primordial Universe, is one of the most important observables in Cosmology. Its recovery is generally carried out by parametric and (semi) blind methods after removing several Galactic and extragalactic emissions. However, in order to take into account their non-linear behaviors, Machine Learning approaches such Neural Networks seem to be promising for that task. In this talk, I will describe how they begin to be an alternative and reliable methods for recovering the Cosmic Microwave Background.

Galactic Archaeology: decoding the fossil record of Galaxy formation and evolution

Sede A. Riccò Via Santa Sofia 78, Catania

One of most important issue in Astrophysics is the achievement of a robust understanding of the sequence of processes that contributed to the building up of the Milky Way. This is obviously important not only "on a local scale" in order to recover the history of formation and evolution of the Galaxy, but also, more in general, for understanding the formation process of spiral galaxies. In the last decade, the advent of high precision photometric and spectroscopic surveys as well as the possibility to estimate, thanks to the ESA Gaia mission, accurate distance for a huge number of field stars, combined with the development of an accurate theoretical framework, is actually opening a new era for this kind of investigations.
We will present some recent results - obtained by using this updated observational and theoretical framework - about the formation and early evolution of the Milky Way.
