A More Complex Than Expected Formation History of the Milky Way's Last Major Merger

Hai-Feng Wang, Guan-Yu Wang, Giovanni Carraro +3

The GaiaSausageEnceladus (GSE) structure, widely recognized as the most recent major accretion event experienced by our Galaxy, is traditionally interpreted as the remnant of…

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 Average Age Map of the Galactic Bulge

Jialu Nie, Martín López-Corredoira, Chao Liu +2

The Galactic Bulge, as the center of the Galaxy, is the closest laboratory for studying galaxy formation and evolution. However, its study faces significant challenges due to heavy…
