[Ifiba] Fwd: coloquio viernes

[Susana Landau]

Hola a todos y todas

Les envio información de un coloquio que se desarrollará este viernes a las
11 hs en el IAFE y que puede ser de interés para varios.

Chervin Laporte (Universidad de Barcelona)

The Galactic stellar halo consists of about 1-2% of the total stellar mass
content of the Milky Way. Yet, it provides important clues on the
formation of the Galaxy, properties of high redshift galaxies through the
study of their resolved stellar populations as well as the nature of dark
matter. In this talk, I will introduce the field of near-field cosmology
and its goals. I will show how the Gaia mission has helped consolidate our
understanding of the formation of the Milky Way but also the nature of
dark matter and how numerical simulations are becoming an important tool
to interpret observational data and the expected avalanche of data from
upcoming spectroscopic/photometric surveys. I will then discuss some of
the work we have carried out in our group on the stellar halo, covering
the formation history of the Milky Way, interpretation of newly discovered
substructures and the interaction of the LMC with the MW through the lens
of numerical simulations.
