Panchromatic Hubble Andromeda Treasury XII. Mapping Stellar Metallicity Distributions in M31
Dylan Gregersen, Anil C. Seth, Benjamin F. Williams +14
We present a study of spatial variations in the metallicity of old red giant branch stars in the Andromeda galaxy. Photometric metallicity estimates are derived by interpolating is…
A Spectroscopic and Photometric Exploration of the C/M Ratio in the Disk of M31
Katherine M. Hamren, Constance M. Rockosi, Puragra Guhathakurta +12
We explore the ratio (C/M) of carbon-rich to oxygen-rich thermally pulsing asymptotic giant branch(TP-AGB) stars in the disk of M31 using a combination of moderate-resolution optic…
Measuring Consistent Masses for 25 Milky Way Globular Clusters
Brian Kimmig, Anil Seth, Inese I. Ivans +4
We present central velocity dispersions, masses, mass to light ratios (s), and rotation strengths for 25 Galactic globular clusters. We derive radial velocities of 1951 stars…
The Panchromatic Hubble Andromeda Treasury X. Ultraviolet to Infrared Photometry of 117 Million Equidistant Stars
Benjamin F. Williams, Dustin Lang, Julianne J. Dalcanton +16
We have measured stellar photometry with the Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3) and Advanced Camera for Surveys (ACS) in near ultraviolet (F275W, F336W), optic…
