RR Lyrae Stars Belonging to the Candidate Globular Cluster Patchick 99

Evan Butler, Andrea Kunder, Zdenek Prudil +16

Patchick 99 is a candidate globular cluster located in the direction of the Galactic bulge, with a proper motion almost identical to the field and extreme field star contamination.…

New candidate hypervelocity red clump stars in the inner Galactic bulge

A. Luna, T. Marchetti, M. Rejkuba +5

We search for high-velocity stars in the inner region of the Galactic bulge using a selected sample of red clump stars. Some of those stars might be considered hypervelocity stars…

The Milky Way Bulge extra-tidal star survey: BH 261 (AL 3)

Andrea Kunder, Zdenek Prudil, Kevin Covey +19

The Milky Way Bulge extra-tidal star survey (MWBest) is a spectroscopic survey with the goal of identifying stripped globular cluster stars from inner Galaxy clusters. In this way,…

The Blanco DECam Bulge Survey (BDBS) VIII: Chemo-kinematics in the southern Galactic bulge from 2.3 million red clump stars with Gaia DR3 proper motions

Tommaso Marchetti, Meridith Joyce, Christian Johnson +5

The Blanco DECam Bulge Survey (BDBS) provides near-ultraviolet to near-infrared photometry for ~250 million unique stars. By combining BDBS photometry with the latest Gaia astromet…

Astrometry in crowded fields towards the Galactic Bulge

Alonso Luna, Tommaso Marchetti, Marina Rejkuba +2

The astrometry towards the Galactic Bulge is hampered by high stellar crowding and patchy extinction. This effect is particularly severe for optical surveys such as Gaia. In this s…

Blanco DECam Bulge Survey (BDBS) IV: Metallicity Distributions and Bulge Structure from 2.6 Million Red Clump Stars

Christian I. Johnson, R. Michael Rich, Iulia T. Simion +12

We present photometric metallicity measurements for a sample of 2.6 million bulge red clump stars extracted from the Blanco DECam Bulge Survey (BDBS). Similar to previous studies,…
