19 Mar 2002 | | Journal: | Astrophys.J. 580 (2002) 16-28 | | Subject: | astro-ph | | Affiliation: | IASF/CNR Sezione di Bologna, Italy | | Abstract: | We study the CMB anisotropy induced by the non-linear perturbations in the massive neutrino density associated to the non-linear gravitational clustering proceses. Our results show that for the neutrino fraction in agreement with that indicated by the astroparticle and nuclear physics experiments and a cosmological accreting mass comparable with the mass of known clusters, the angular resolution and the sensitivity of the CMB anisotropy measurements from the Planck surveyor will allow the detection of the dynamical effects of the neutrino gravitational clustering. | | Source: | arXiv, astro-ph/0203306 | | Services: | Forum | Review | PDF | Favorites | |
