4 Dec 2004 | | Journal: | Phys.Rev. D72 (2005) 083001 | | Subject: | astro-ph | | Affiliation: | 1,2 and 3) and Pengjie Zhang ( Fermilab, University of Chicago, Northwestern | | Abstract: | Weak gravitational lensing of background galaxies offers an excellent opportunity to study the intervening distribution of matter. While much attention to date has focused on the two-point function of the cosmic shear, the three-point function, the {it bispectrum}, also contains very useful cosmological information. Here, we compute three corrections to the bispectrum which are nominally of the same order as the leading term. We show that the corrections are small, so they can be ignored when analyzing present surveys. However, they will eventually have to be included for accurate parameter estimates from future surveys. | | Source: | arXiv, astro-ph/0501063 | | Services: | Forum | Review | PDF | Favorites | |
