Dark Energy Survey Year 1 Results: Calibration of redMaGiC Redshift Distributions in DES and SDSS from Cross-Correlations
R. Cawthon, C. Davis, M. Gatti +88
We present calibrations of the redshift distributions of redMaGiC galaxies in the Dark Energy Survey Year 1 (DES Y1) and Sloan Digital Sky Survey (SDSS) DR8 data. These results det…
Dark Energy Survey Year 1 Results: Cross-Correlation Redshifts in the DES -- Calibration of the Weak Lensing Source Redshift Distributions
C. Davis, M. Gatti, P. Vielzeuf +81
We present the calibration of the Dark Energy Survey Year 1 (DES Y1) weak lensing source galaxy redshift distributions from clustering measurements. By cross-correlating the positi…
Dark Energy Survey Year 1 Results: Cross-Correlation Redshifts - Methods and Systematics Characterization
M. Gatti, P. Vielzeuf, C. Davis +104
We use numerical simulations to characterize the performance of a clustering-based method to calibrate photometric redshift biases. In particular, we cross-correlate the weak lensi…
Dark Energy Survey Year 1 Results: Cosmological Constraints from Cosmic Shear
M. A. Troxel, N. MacCrann, J. Zuntz +132
We use 26 million galaxies from the Dark Energy Survey (DES) Year 1 shape catalogs over 1321 deg of the sky to produce the most significant measurement of cosmic shear in a gal…
Dark Energy Survey Year 1 Results: Galaxy-Galaxy Lensing
J. Prat, C. Sánchez, Y. Fang +112
We present galaxy-galaxy lensing measurements from 1321 sq. deg. of the Dark Energy Survey (DES) Year 1 (Y1) data. The lens sample consists of a selection of 660,000 red galaxies w…
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…
