The Milky Way as the frontier laboratory for cosmology
Četvrtak/Thursday 09.12.2021. u 13:15 h
Fizički odsjek, F-13 and online
The Milky Way is a stepping stone to understanding galaxies and the
universe. Being a typical galaxy, inferring events in its history helps
to develop the overall theory of galaxy formation. Further, since the
effects of dark matter are observable in individual stars, the Milky Way
provides an excellent setting for testing the nature of dark matter. So
far, the progress on these fundamental topics has been made
predominantly by studying the spatial distribution of different stellar
populations. Now, the Gaia mission is revolutionizing the way we view
our Galaxy by delivering precise proper motions, complemented by radial
velocity measurements from ground-based spectroscopic surveys like
SDSS-V. I will discuss how I dynamically model the 3D positions and
velocities that these datasets provide for millions of stars to
constrain the formation history of the Milky Way, the small-scale
structure of its dark matter halo, and the particle nature of dark
matter.
