Shear‐selected Cluster Cosmology: Tomography and Optimal Filtering
Shear‐selected Cluster Cosmology: Tomography and Optimal Filtering
We study the potential of weak-lensing surveys to detect clusters of galaxies, using a fast particle-mesh cosmological N-body simulation algorithm specifically tailored to investigate the statistics of these shear-selected clusters. In particular, we explore the degree to which the radial positions of galaxy clusters can be determined tomographically, by using …
