The SAGA Survey: I. Satellite Galaxy Populations Around Eight Milky Way Analogs
Marla Geha, Risa H. Wechsler, Yao-Yuan Mao +8
We present the survey strategy and early results of the "Satellites Around Galactic Analogs" (SAGA) Survey. The SAGA Survey's goal is to measure the distribution of satellite galax…
Environmental dependence of the galaxy stellar mass function in the Dark Energy Survey Science Verification Data
J. Etherington, D. Thomas, C. Maraston +61
Measurements of the galaxy stellar mass function are crucial to understand the formation of galaxies in the Universe. In a hierarchical clustering paradigm it is plausible that the…
Globular Cluster Abundances from High-Resolution, Integrated-Light Spectroscopy. II. Expanding the Metallicity Range for Old Clusters and Updated Analysis Techniques
J. E. Colucci, R. A. Bernstein, A. McWilliam
We present abundances of globular clusters in the Milky Way and Fornax from integrated light spectra. Our goal is to evaluate the consistency of the integrated light analysis relat…
Galaxy Populations in Massive Galaxy Clusters to z=1.1: Color Distribution, Concentration, Halo Occupation Number and Red Sequence Fraction
C. Hennig, J. J. Mohr, A. Zenteno +70
We study the galaxy populations in 74 Sunyaev Zeldovich Effect (SZE) selected clusters from the South Pole Telescope (SPT) survey that have been imaged in the science verification…
Eight New Milky Way Companions Discovered in First-Year Dark Energy Survey Data
The DES Collaboration, K. Bechtol, A. Drlica-Wagner +91
We report the discovery of eight new Milky Way companions in ~1,800 deg^2 of optical imaging data collected during the first year of the Dark Energy Survey (DES). Each system is id…
The LMC geometry and outer stellar populations from early DES data
Eduardo Balbinot, B. X. Santiago, L. Girardi +50
The Dark Energy Camera has captured a large set of images as part of Science Verification (SV) for the Dark Energy Survey. The SV footprint covers a lar ge portion of the outer Lar…
Evidence for Two Distinct Stellar Initial Mass Functions : Probing for Clues to the Dichotomy
Dennis Zaritsky, Janet E. Colucci, Peter M. Pessev +2
We present new measurements of the velocity dispersions of eleven Local Group globular clusters using spatially integrated spectra, to expand our sample of clusters with precise in…
Evidence for Two Distinct Stellar Initial Mass Functions
Dennis Zaritsky, Janet E. Colucci, Peter M. Pessev +2
We present velocity dispersion measurements of 20 Local Group stellar clusters (7 < log(age [yrs]) < 10.2) from integrated light spectra and examine the evolution of the stellar ma…
Globular Cluster Abundances from High-Resolution, Integrated-Light Spectroscopy. III. The Large Magellanic Cloud: Fe and Ages
J. E. Colucci, R. A. Bernstein, S. A. Cameron +1
In this paper we refine our method for the abundance analysis of high resolution spectroscopy of the integrated light of unresolved globular clusters (GCs). This method was previou…
M31 Globular Cluster Abundances from High-Resolution, Integrated-Light Spectroscopy
J. E. Colucci, R. A. Bernstein, S. Cameron +2
We report the first detailed chemical abundances for 5 globular clusters (GCs) in M31 from high-resolution (R ~ 25,000) spectroscopy of their integrated light. These GCs are the fi…
