Tracing the kinematic perturbations of the Milky Way spiral arms with APOGEE DR17 and Gaia DR3
Xi-Can Tang, Zhi Li, Iulia T. Simion +4
Aims. We constrain the dynamical perturbations of the spiral arms in the Milky Way disk, based on the non-axisymmetric streaming motions of RGB stars revealed by APOGEE and \textit…
The Average Age Map of the Galactic Bulge
Jialu Nie, MartÃn 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…
The Milky Way Bulge Extra-Tidal Star Survey: NGC 6569
Joanne Hughes, Andrea Kunder, Kevin Covey +25
We present spectroscopic evidence for tidal debris associated with the bulge globular cluster NGC 6569, based on medium-resolution (R ~ 11,000) Anglo-Australian Telescope spectra o…
Insight into the Galactic Bulge Chemodynamical Properties from Gaia DR3
Xiaojie Liao, Zhaoyu Li, Iulia Simion +4
We explore the chemodynamical properties of the Galaxy in the azimuthal velocity and metallicity [Fe/H] space using red giant stars from Gaia Data Release 3. The row-normali…
