Towards Unveiling the Origins of the Milky Way Bulge through Multi-band-Messenger Sky Surveys

Hai-Feng Wang, Xiao Han, Giovanni Carraro +3

We analyze the structure and chemo-dynamical properties of the Galactic bulge using ab-type RR Lyrae stars (RRabs) from OGLE-IV and giant stars from APOGEE and Gaia. Orbital integr…
