Mc Cracken(10) O. Le Fevre(10) ( IAP Paris, Obs. Paris (DEMIRM), CITA Toronto, MPA Garching, Univ. Bonn, SPhT | | Abstract: | The first detections of cosmic shear signal reported recently by 4 independent groups cover angular scales between one and 10 arcmin. On those scales, the cosmic shear is a signature of non-linear perturbations, like groups and clusters of galaxies. We present the results obtained by our team on CFHT and on the VLT and discuss its impact for the analysis of cluster abundances and cosmology | | Source: | arXiv, astro-ph/0010008 | | Services: | Forum | Review | PDF | Favorites | |
