"From Building Blocks to Large Galaxies: Towards Understanding the Formation of the Milky Way" The early chemical evolution of the Galaxy and the Universe is vital
to our understanding of a host of astrophysical phenomena. Since the
oldest, most metal-poor stars are relics from the high-redshift
universe, they probe the chemical and dynamical conditions of a time
when large galaxies first began to assemble. Recent works have shown
that the ultra-faint dwarf galaxies (with L<10^5Lsun) contain a
relatively large fraction of extremely metal-poor stars and are devoid
of solar-metallicity stars. This reflects a rather short or truncated
star formation history similar to what one would expect to occur in a
first/early galaxy. The chemical signatures of these dwarfs
furthermore support the concept that small systems analogous to the
surviving ultra-faint galaxies were the building blocks of the Milky
Way's low-metallicity halo. This opens a new window for studying
galaxy formation with the means of stellar chemical analyses. Massachusetts Institute of Technology host: Volker Bromm |
