Observation and Confirmation of Six Strong Lensing Systems in The Dark Energy Survey Science Verification Data
B. Nord, E. Buckley-Geer, H. Lin +89
We report the observation and confirmation of the first group- and cluster-scale strong gravitational lensing systems found in Dark Energy Survey (DES) data. Through visual inspect…
Physical properties of star clusters in the outer LMC as observed by the Dark Energy Survey
A. Pieres, B. Santiago, E. Balbinot +57
The Large Magellanic Cloud (LMC) harbors a rich and diverse system of star clusters, whose ages, chemical abundances, and positions provide information about the LMC history of sta…
Photometric redshifts and clustering of emission line galaxies selected jointly by DES and eBOSS
S. Jouvel, T. Delubac, J. Comparat +65
We present the results of the first test plates of the extended Baryon Oscillation Spectroscopic Survey. This paper focuses on the emission line galaxies (ELG) population targetted…
Discovery of a Stellar Overdensity in Eridanus-Phoenix in the Dark Energy Survey
T. S. Li, E. Balbinot, N. Mondrik +56
We report the discovery of an excess of main sequence turn-off stars in the direction of the constellations of Eridanus and Phoenix from the first year data of the Dark Energy Surv…
The Phoenix stream: a cold stream in the Southern hemisphere
E. Balbinot, B. Yanny, T. S. Li +49
We report the discovery of a stellar stream in the Dark Energy Survey (DES) Year 1 (Y1A1) data. The discovery was made through simple color-magnitude filters and visual inspection…
Digging deeper into the Southern skies: a compact Milky-Way companion discovered in first-year Dark Energy Survey data
E. Luque, A. Queiroz, B. Santiago +61
The Dark Energy Survey (DES) is a 5000 sq. degree survey in the southern hemisphere, which is rapidly reducing the existing north-south asymmetry in the census of MW satellites and…
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…
Mapping and simulating systematics due to spatially-varying observing conditions in DES Science Verification data
B. Leistedt, H. V. Peiris, F. Elsner +92
Spatially-varying depth and characteristics of observing conditions, such as seeing, airmass, or sky background, are major sources of systematic uncertainties in modern galaxy surv…
Observation of Two New L4 Neptune Trojans in the Dark Energy Survey Supernova Fields
D. W. Gerdes, R. J. Jennings, G. M. Bernstein +62
We report the discovery of the eighth and ninth known Trojans in stable orbits around Neptune's leading Lagrange point, L4. The objects 2014 QO and 2014 QP were det…
Cosmic Shear Measurements with DES Science Verification Data
M. R. Becker, M. A. Troxel, N. MacCrann +102
We present measurements of weak gravitational lensing cosmic shear two-point statistics using Dark Energy Survey Science Verification data. We demonstrate that our results are robu…
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…
OzDES multi-fibre spectroscopy for the Dark Energy Survey: first-year operation and results
Fang Yuan, C. Lidman, T. M. Davis +99
OzDES is a five-year, 100-night, spectroscopic survey on the Anglo-Australian Telescope, whose primary aim is to measure redshifts of approximately 2,500 Type Ia supernovae host ga…
The Dark Energy Camera
B. Flaugher, H. T. Diehl, K. Honscheid +115
The Dark Energy Camera is a new imager with a 2.2-degree diameter field of view mounted at the prime focus of the Victor M. Blanco 4-meter telescope on Cerro Tololo near La Serena,…
Automated Transient Identification in the Dark Energy Survey
D. A. Goldstein, C. B. D'Andrea, J. A. Fischer +64
We describe an algorithm for identifying point-source transients and moving objects on reference-subtracted optical images containing artifacts of processing and instrumentation. T…
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…
Search for Gamma-Ray Emission from DES Dwarf Spheroidal Galaxy Candidates with Fermi-LAT Data
LAT Collaboration, The DES Collaboration, A. Drlica-Wagner +123
Due to their proximity, high dark-matter content, and apparent absence of non-thermal processes, Milky Way dwarf spheroidal satellite galaxies (dSphs) are excellent targets for the…
