Title:     Cosmic Neutrino Background Anisotropy Spectrum

Abstract: Studying the Cosmic Microwave Background (CMB) anisotropies provides us with detailed information about the physical content of the Universe. Standard model also provides us with cosmic neutrino background (CNB), the relic neutrinos which traveled to us freely from when the Universe was only less than one second old. We study the anisotropy of the cosmic neutrino background for both massless and massive neutrinos. Assuming the normal hierarchy for neutrino masses, the CNB power spectrum is calculated and it’s shown that there is some resemblance between neutrino power spectrum and the usual CMB spectrum as both have acoustic oscillations and silk damping.
