Drage kolegice i kolege,
drago nam je da vas možemo pozvati na sljedeći seminar Fizičkog odsjeka:

Dear colleagues,
we would like to invite you to the following Department of Physics seminar:

Četvrtak/Thursday *09.12.2021. u 13:15 h*
Fizički odsjek, *F-13 and online*

Ana Bonaca, staff scientist
Carnegie Observatories, Pasadena, California, USA


The Milky Way as the frontier laboratory for cosmology

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.

Note:
Studenti na kolegiju Fizika zvijezda prate seminar u F13, a ostali kao
webinar na Zoom linku: / students in the Physics of Stars class will attend
the seminar in person, and we kindly ask everyone else to use the zoom link:
