Cosmic shear and halo abundances: Analytical versus numerical results
Katrin Reblinsky, Guido Kruse, Bhuvnesh Jain +1
The aperture mass has been shown in a series of recent publications to be a useful quantitative tool for weak lensing studies, ranging from cosmic shear to the detection of a mass-…
The non-Gaussian tail of cosmic-shear statistics
Guido Kruse, Peter Schneider
Due to gravitational instability, an initially Gaussian density field develops non-Gaussian features as the Universe evolves. The most prominent non-Gaussian features are massive h…
Statistics of dark matter haloes expected from weak lensing surveys
Guido Kruse, Peter Schneider
The distortion of the images of faint high-redshift galaxies can be used to probe the intervening mass distribution. This weak gravitational lensing effect has been used recently t…
A new measure for cosmic shear
Peter Schneider, Ludovic van Waerbeke, Bhuvnesh Jain +1
We consider here a new statistical measure for cosmic shear, the aperture mass Map, which is defined as a spatially filtered projected density field and which can be measured direc…
