Euclid: Effect of sample covariance on the number counts of galaxy clusters
A. Fumagalli, A. Saro, S. Borgani +93
Aims. We investigate the contribution of shot-noise and sample variance to the uncertainty of cosmological parameter constraints inferred from cluster number counts in the context…
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…
Testing the Reliability of Fast Methods for Weak Lensing Simulations: WL-MOKA on PINOCCHIO
Carlo Giocoli, Pierluigi Monaco, Lauro Moscardini +4
The generation of simulated convergence maps is of key importance in fully exploiting weak lensing by Large Scale Structure (LSS) from which cosmological parameters can be derived.…
