The Sunyaev-Zel'dovich Effect in CMB-calibrated Theories Applied to the Cosmic Background Imager Anisotropy Power at l > 2000
Abstract
We discuss the nature of the possible high-l excess in the cosmic microwave background (CMB) anisotropy power spectrum observed by the Cosmic Background Imager (CBI). We probe the angular structure of the excess in the CBI deep fields and investigate whether it could be due to the scattering of CMB photons by hot electrons within clusters, which is the Sunyaev-Zel'dovich (SZ) effect. We estimate the density fluctuation parameters for amplitude, …
