Effects of Cosmological Magnetic Helicity on the CMB | | Tina Kahniashvili (Kansas State University
; Center for Plasma Astrophysics
; | | Date: |
5 Oct 2005 | | Affiliation: | Kansas State University (USA) and Center for Plasma Astrophysics (Georgia) | | Abstract: | In this talk I present a short review of primordial magnetic helicity effects on Cosmic Microwave Background (CMB) temperature and polarization anisotropies. These effects allow us to test for cosmological magnetic helicity, however, very accurate CMB fluctuation data is required. This scheme for magnetic helicity detection is valid only for a cosmological magnetic field with a present amplitude larger than $10^{-9}-10^{-10}$ Gauss. | | Source: | arXiv, astro-ph/0510151 | | Services: | Forum | Review | PDF | Favorites | |
