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.…

An Optical Search for New Outbursting Low Mass X-Ray Binaries

Yuankun Wang, Eric C. Bellm, Allison Crossland +5

Transient Low-Mass X-ray binaries (LMXBs) are discovered largely by X-ray and gamma-ray all-sky monitors. The X-ray outburst is also accompanied by an optical brightening, which em…

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…

The Blanco DECam Bulge Survey. I. The Survey Description and Early Results

R. Michael Rich, Christian I. Johnson, Michael Young +18

The Blanco Dark Energy Camera (DECam) Bulge survey is a Vera Rubin Observatory (LSST) pathfinder imaging survey, spanning sq. deg. of the Southern Galactic bulge, $-2^\c…

Chemically-dissected rotation curves of the Galactic Bulge from Main Sequence proper motions

William I. Clarkson, Annalisa Calamida, Kailash C. Sahu +9

We report results from an exploratory study implementing a new probe of Galactic evolution using archival Hubble Space Telescope imaging observations. Precise proper motions are co…

A Chemical Composition Survey of the Iron-Complex Globular Cluster NGC 6273 (M 19)

Christian I. Johnson, Nelson Caldwell, R. Michael Rich +5

Recent observations have shown that a growing number of the most massive Galactic globular clusters contain multiple populations of stars with different [Fe/H] and neutron-capture…

The First Detection of Blue Straggler Stars in the Milky Way Bulge

William I. Clarkson, Kailash C. Sahu, Jay Anderson +8

We report the first detections of Blue Straggler Stars (BSS) in the bulge of the Milky Way galaxy. Proper motions from extensive space-based observations along a single sight-line…
