Galaxy bias from the Dark Energy Survey Science Verification data: combining galaxy density maps and weak lensing maps
C. Chang, A. Pujol, E. Gaztanaga +80
We measure the redshift evolution of galaxy bias for a magnitude-limited galaxy sample by combining the galaxy density maps and weak lensing shear maps for a 116 deg ar…
Assessment of Systematic Chromatic Errors that Impact Sub-1% Photometric Precision in Large-Area Sky Surveys
T. S. Li, D. L. DePoy, J. L. Marshall +69
Meeting the science goals for many current and future ground-based optical large-area sky surveys requires that the calibrated broadband photometry is stable in time and uniform ov…
Wide-Field Lensing Mass Maps from DES Science Verification Data
C. Chang, V. Vikram, B. Jain +81
We present a mass map reconstructed from weak gravitational lensing shear measurements over 139 sq. deg from the Dark Energy Survey (DES) Science Verification data. The mass map pr…
Wide-Field Lensing Mass Maps from DES Science Verification Data: Methodology and Detailed Analysis
V. Vikram, C. Chang, B. Jain +91
Weak gravitational lensing allows one to reconstruct the spatial distribution of the projected mass density across the sky. These "mass maps" provide a powerful tool for studying c…
