Cosmic Shear Measurements with DES Science Verification Data
M. R. Becker, M. A. Troxel, N. MacCrann +102
We present measurements of weak gravitational lensing cosmic shear two-point statistics using Dark Energy Survey Science Verification data. We demonstrate that our results are robu…
Accurate photometric redshift probability density estimation - method comparison and application
Markus Michael Rau, Stella Seitz, Fabrice Brimioulle +4
We introduce an ordinal classification algorithm for photometric redshift estimation, which significantly improves the reconstruction of photometric redshift probability density fu…
Cosmic variance of the galaxy cluster weak lensing signal
D. Gruen, S. Seitz, M. R. Becker +2
Intrinsic variations of the projected density profiles of clusters of galaxies at fixed mass are a source of uncertainty for cluster weak lensing. We present a semi-analytical mode…
