Subproject A11: Chemo-Dynamical Mapping of the Galactic Bulge

Eva K. Grebel (ARI), Andreas Koch (ARI)

The Galactic bulge is one of the oldest, yet very metal-rich components of the Milky Way and its formation is yet unclear. Here, we aim to exploit large-scale photometric and spectroscopic surveys using a variety of stellar tracers in order to pin down the origin of the bulge, constrain its formation time, and separate its old and intermediate-age populations from the surrounding disk and spheroid. To this end, the time-domain survey „VISTA Variables in The Via Lactea“ (VVV) is fundamental for extending the old RR Lyrae population, while we will address the chemo-dynamical history across the bulge’s complex metallicity distribution using proprietary access to near-infra-red SDSS-V spectra.
