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…

The Baryonic Mass Estimates of the Milky Way Halo in the form of High Velocity Clouds
Noraiz Tahir, Martin Lopez Corredoira, Francesco De Paolis
The halo of our Galaxy is populated with a significant number of high-velocity clouds (HVCs) moving with a speed up to km/s. It is suggested that these HVCs might contain a n…
