The Intrinsic Alignment of Red Galaxies in DES Y1 redMaPPer Galaxy Clusters
C. Zhou, A. Tong, M. A. Troxel +79
Clusters of galaxies are sensitive to the most nonlinear peaks in the cosmic density field. The weak gravitational lensing of background galaxies by clusters can allow us to infer…

Dark Energy Survey Year 1 Results: Wide field mass maps via forward fitting in harmonic space
B. Mawdsley, D. Bacon, C. Chang +63
We present new wide-field weak lensing mass maps for the Year 1 Dark Energy Survey data, generated via a forward fitting approach. This method of producing maps does not impose any…

Cosmological lensing ratios with DES Y1, SPT and Planck
J. Prat, E. J. Baxter, T. Shin +131
Correlations between tracers of the matter density field and gravitational lensing are sensitive to the evolution of the matter power spectrum and the expansion rate across cosmic…
