DESI Observations of the Andromeda Galaxy: Revealing the Immigration History of our Nearest Neighbor
Arjun Dey, Joan R. Najita, S. E. Koposov +45
We present DESI observations of the inner halo of M31, which reveal the kinematics of a recent merger - a galactic immigration event - in exquisite detail. Of the 11,416 sources st…
Milky Way Satellite Census. IV. Constraints on Decaying Dark Matter from Observations of Milky Way Satellite Galaxies
S. Mau, E. O. Nadler, R. H. Wechsler +66
We use a recent census of the Milky Way (MW) satellite galaxy population to constrain the lifetime of particle dark matter (DM). We consider two-body decaying dark matter (DDM) in…
Dark Energy Survey Year 1 Results: The Impact of Galaxy Neighbours on Weak Lensing Cosmology with im3shape
S. Samuroff, S. L. Bridle, J. Zuntz +68
We use a suite of simulated images based on Year 1 of the Dark Energy Survey to explore the impact of galaxy neighbours on shape measurement and shear cosmology. The hoopoe image s…
Dark Energy Survey Year 1 Results: Curved-Sky Weak Lensing Mass Map
C. Chang, A. Pujol, B. Mawdsley +117
We construct the largest curved-sky galaxy weak lensing mass map to date from the DES first-year (DES Y1) data. The map, about 10 times larger than previous work, is constructed ov…
Dark Energy Survey Year 1 Results: Weak Lensing Shape Catalogues
J. Zuntz, E. Sheldon, S. Samuroff +104
We present two galaxy shape catalogues from the Dark Energy Survey Year 1 data set, covering 1500 square degrees with a median redshift of . The catalogues cover two main fie…
Dark Energy Survey Year 1 Results: Photometric Data Set for Cosmology
A. Drlica-Wagner, I. Sevilla-Noarbe, E. S. Rykoff +86
We describe the creation, content, and validation of the Dark Energy Survey (DES) internal year-one cosmology data set, Y1A1 GOLD, in support of upcoming cosmological analyses. The…
A Measurement of CMB Cluster Lensing with SPT and DES Year 1 Data
E. J. Baxter, S. Raghunathan, T. M. Crawford +118
Clusters of galaxies gravitationally lens the cosmic microwave background (CMB) radiation, resulting in a distinct imprint in the CMB on arcminute scales. Measurement of this effec…
Cross-Correlation Redshift Calibration Without Spectroscopic Calibration Samples in DES Science Verification Data
C. Davis, E. Rozo, A. Roodman +74
Galaxy cross-correlations with high-fidelity redshift samples hold the potential to precisely calibrate systematic photometric redshift uncertainties arising from the unavailabilit…
Discovery of the Lensed Quasar System DES J0408-5354
H. Lin, E. Buckley-Geer, A. Agnello +78
We report the discovery and spectroscopic confirmation of the quad-like lensed quasar system DES J0408-5354 found in the Dark Energy Survey (DES) Year 1 (Y1) data. This system was…
An Ultra-Faint Galaxy Candidate Discovered in Early Data from the Magellanic Satellites Survey
A. Drlica-Wagner, K. Bechtol, S. Allam +21
We report a new ultra-faint stellar system found in Dark Energy Camera data from the first observing run of the Magellanic Satellites Survey (MagLiteS). MagLiteS J0644-5953 (Pictor…
Comparing Dark Energy Survey and HST-CLASH observations of the galaxy cluster RXC J2248.7-4431: implications for stellar mass versus dark matter
A. Palmese, O. Lahav, M. Banerji +65
We derive the stellar mass fraction in the galaxy cluster RXC J2248.7-4431 observed with the Dark Energy Survey (DES) during the Science Verification period. We compare the stellar…
Redshift distributions of galaxies in the DES Science Verification shear catalogue and implications for weak lensing
C. Bonnett, M. A. Troxel, W. Hartley +104
We present photometric redshift estimates for galaxies used in the weak lensing analysis of the Dark Energy Survey Science Verification (DES SV) data. Four model- or machine learni…
The DES Science Verification Weak Lensing Shear Catalogues
M. Jarvis, E. Sheldon, J. Zuntz +92
We present weak lensing shear catalogues for 139 square degrees of data taken during the Science Verification (SV) time for the new Dark Energy Camera (DECam) being used for the Da…
CMB lensing tomography with the DES Science Verification galaxies
T. Giannantonio, P. Fosalba, R. Cawthon +101
We measure the cross-correlation between the galaxy density in the Dark Energy Survey (DES) Science Verification data and the lensing of the cosmic microwave background (CMB) as re…
Galaxy clustering, photometric redshifts and diagnosis of systematics in the DES Science Verification data
M. Crocce, J. Carretero, A. H. Bauer +84
We study the clustering of galaxies detected at in the Science Verification observations of the Dark Energy Survey (DES). Two-point correlation functions are measured usin…
Constraints on the Richness-Mass Relation and the Optical-SZE Positional Offset Distribution for SZE-Selected Clusters
A. Saro, S. Bocquet, E. Rozo +99
We cross-match galaxy cluster candidates selected via their Sunyaev-Zel'dovich effect (SZE) signatures in 129.1 deg of the South Pole Telescope 2500d SPT-SZ survey with optical…
