Abstract

We present galaxy-galaxy lensing results from 139 square degrees of Dark Energy Survey(DES) Science Verification (SV) data. Our lens sample consists of red galaxies, known asredMaGiC, which are specifically selected to have a low photometric redshift error and outlierrate. The lensing measurement has a total signal-to-noise of 29 over scales 0:09 < R < 15Mpc/h, including all lenses over a wide redshift range 0:2 < z < 0:8. Dividing the lenses intothree redshift bins for this constant moving number density sample, we find no evidence forevolution in the halo mass with redshift.We obtain consistent results for the lensing measurementwith two independent shear pipelines, ngmix and im3shape. We perform a numberof null tests on the shear and photometric redshift catalogs and quantify resulting systematicuncertainties. Covariances from jackknife subsamples of the data are validated with a suite of50 mock surveys. The results and systematics checks in this work provide a critical input forfuture cosmological and galaxy evolution studies with the DES data and redMaGiC galaxysamples. We fit a Halo Occupation Distribution (HOD) model, and demonstrate that our dataconstrains the mean halo mass of the lens galaxies, despite strong degeneracies between individualHOD parameters.
