The Splashback Feature around DES Galaxy Clusters: Galaxy Density and Weak Lensing Profiles
C. Chang, E. Baxter, B. Jain +82
Splashback refers to the process of matter that is accreting onto a dark matter halo reaching its first orbital apocenter and turning around in its orbit. The cluster-centric radiu…
Density split statistics: Cosmological constraints from counts and lensing in cells in DES Y1 and SDSS data
D. Gruen, O. Friedrich, E. Krause +93
We derive cosmological constraints from the probability distribution function (PDF) of evolved large-scale matter density fluctuations. We do this by splitting lines of sight by de…
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: 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…
