Impact of baryons in cosmic shear analyses with tomographic aperture mass statistics
Nicolas Martinet, Tiago Castro, Joachim Harnois-Déraps +3
NonGaussian cosmic shear statistics based on weak-lensing aperture mass () maps can outperform the classical shear two-point correlation function (-2PCF) in terms of…
Cosmic Shear Cosmology Beyond 2-Point Statistics: A Combined Peak Count and Correlation Function Analysis of DES-Y1
Joachim Harnois-Déraps, Nicolas Martinet, Tiago Castro +5
We constrain cosmological parameters from a joint cosmic shear analysis of peak-counts and the two-point shear correlation functions, as measured from the Dark Energy Survey (DES-Y…
Probing dark energy with tomographic weak-lensing aperture mass statistics
Nicolas Martinet, Joachim Harnois-Déraps, Eric Jullo +1
We forecast and optimize the cosmological power of various weak-lensing aperture mass () map statistics for future cosmic shear surveys, including peaks, voids, and the…
Constraining the masses of high-redshift clusters with weak lensing: Revised shape calibration testing for the impact of stronger shears and increased blending
B. Hernandez-Martin, T. Schrabback, H. Hoekstra +7
WL measurements have well-known shear estimation biases, which can be partially corrected for with the use of image simulations. We present an analysis of simulated images that mim…
