Eight Ultra-faint Galaxy Candidates Discovered in Year Two of the Dark Energy Survey
The DES Collaboration, A. Drlica-Wagner, K. Bechtol +74
We report the discovery of eight new ultra-faint dwarf galaxy candidates in the second year of optical imaging data from the Dark Energy Survey (DES). Six of these candidates are d…
The Difference Imaging Pipeline for the Transient Search in the Dark Energy Survey
R. Kessler, J. Marriner, M. Childress +60
We describe the difference imaging pipeline (DiffImg) used to detect transients in deep images from the Dark Energy Survey Supernova program (DES-SN) in its first observing season…
Stellar Kinematics and Metallicities in the Ultra-Faint Dwarf Galaxy Reticulum II
J. D. Simon, A. Drlica-Wagner, T. S. Li +69
We present Magellan/M2FS, VLT/GIRAFFE, and Gemini South/GMOS spectroscopy of the newly discovered Milky Way satellite Reticulum II. Based on the spectra of 25 Ret II member stars s…
