Mercoledi 12 febbraio alle ore 11:00, presso l’Aula Seminari dell’osservatorio, il prof. Santi Cassisi dell’INAF-Osservatorio Astronomico d’Abruzzo, terrà il seminario dal titolo “Decoding the fossil record of Galaxy formation“.

Abstract

One of the most important issues in Astrophysics is the achievement of a robust understanding of the process or 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, 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 Gaia mission, accurate distance for a huge number of field stars is actually opening a new era for this kind of investigations.
In this seminar, I will review the common scenarios for the formation of the Milky Way, and present some recent results – obtained by using an updated observational framework – about the early phases of the Milky Way formation and evolution.
