and patchy extinction. This effect is particularly severe for optical surveys such as the …

Blanco DECam Bulge Survey (BDBS). VII. Multiple Populations in Globular Clusters of the Galactic Bulge

JA Kader, CA Pilachowski, CI Johnson… - The Astrophysical …, 2022 - iopscience.iop.org
We present photometric evidence for multiple stellar populations (MPs) in 14 globular
clusters (GCs) toward the southern Galactic bulge. The photometric data come as part of the …

RR Lyrae Stars Belonging to the Candidate Globular Cluster Patchick 99

E Butler, A Kunder, Z Prudil, KR Covey… - The Astrophysical …, 2024 - iopscience.iop.org
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. A recent …
