Probing Intracluster Magnetic Fields with Cosmic Microwave Background Polarization
Intracluster magnetic fields with ∼ μG strength induce Faraday rotation on the cosmic microwave background (CMB) polarization. Measurements of this effect can potentially probe the detailed structure of intracluster magnetic fields across clusters, since the CMB polarization is a continuously varying field on the sky, in contrast to the conventional method restricted by the limited number of ra...
متن کاملCosmic microwave background polarization signals from tangled magnetic fields.
Tangled, primordial cosmic magnetic fields create small rotational velocity perturbations on the last scattering surface of the cosmic microwave background radiation. For fields which redshift to a present value of B0 = 3 x 10(-9) G, these vector modes are shown to generate polarization anisotropies of order 0.1-4 microK on small angular scales (500<l<2000), assuming delta function or a power l...
متن کاملFaraday Rotation Effect of Intracluster Magnetic Field on Cosmic Microwave Background Polarization
The observed magnetic field of microgauss strength in clusters of galaxies should induce the Faraday rotation effect on the linearly polarized cosmic microwave background (CMB) radiation when the CMB radiation propagates through a cluster at low redshift. The Faraday rotation arises from combined contributions of the magnetic field strength, the electron density, the cluster size, and the chara...
متن کاملCosmic Microwave Background Polarization
Cosmic microwave background (CMB) anisotropy is our richest source of cosmological information; the standard cosmological model was largely established thanks to study of the temperature anisotropies. By the end of the decade, the Planck satellite will close this important chapter and move us deeper into the new frontier of polarization measurements. Numerous ground–based and balloon–borne expe...
متن کاملCosmic microwave background polarization analysis
With polarization of the cosmic microwave background (CMB) now detected, and confirmed by several independent experiments, the next goal is to characterise accurately its statistical properties. In these lecture notes we review the physical motivation for pursuing CMB polarization, and the basic statistical properties of the polarization fields. We then discuss some of the key aspects of the an...
