Comparing the Quenching Times of Faint M31 and Milky Way Satellite Galaxies

Daniel R. Weisz, Nicolas F. Martin, Andrew E. Dolphin +8

We present the star formation histories (SFHs) of 20 faint M31 satellites () that were measured by modeling sub-horizontal branch (HB) depth color-mag…

Star formation at the edge of the Local Group: a rising star formation history in the isolated galaxy WLM

Saundra M. Albers, Daniel R. Weisz, Andrew A. Cole +11

We present the star formation history (SFH) of the isolated (D~970 kpc) Local Group dwarf galaxy WLM measured from color-magnitude diagrams constructed from deep Hubble Space Teles…

Hubble Space Telescope Imaging of Antlia B: Star Formation History and a New Tip of the Red Giant Branch Distance

Jonathan R. Hargis, S. Albers, D. Crnojević +8

A census of the satellite population around dwarf galaxy primary hosts in environments outside the Local Group is essential to understanding CDM galaxy formation and evolution o…

The Unusual Initial Mass Function of the Arches Cluster

M. W. Hosek, J. R. Lu, J. Anderson +5

As a young massive cluster in the Central Molecular Zone, the Arches cluster is a valuable probe of the stellar Initial Mass Function (IMF) in the extreme Galactic Center environme…

The Optical/Near-Infrared Extinction Law In Highly Reddened Regions

M. W. Hosek, J. R. Lu, J. Anderson +6

A precise extinction law is a critical input when interpreting observations of highly reddened sources such as young star clusters and the Galactic Center (GC). We use Hubble Space…

A rogues gallery of Andromeda's dwarf galaxies I. A predominance of red horizontal branches

Nicolas F. Martin, Daniel R. Weisz, Saundra M. Albers +11

We present homogeneous, sub-horizontal branch photometry of twenty dwarf spheroidal satellite galaxies of M31 observed with the Hubble Space Telescope. Combining our new data for s…

An Improved Distance and Mass Estimate for Sgr A* from a Multistar Orbit Analysis

A. Boehle, A. M. Ghez, R. Schödel +11

We present new, more precise measurements of the mass and distance of our Galaxy's central supermassive black hole, Sgr A*. These results stem from a new analysis that more than do…
