Connecting Cosmology and Galaxy Evolution with the Clustering of High-Redshift Dusty Star-Forming Galaxies
November 16, 2011
Abstract: The clustering of high-redshift dusty star-forming galaxies (DSFGs) is currently of interest both as a foreground for Cosmic Microwave Background analysis and for studying galaxy evolution. I will present recent work in which I combine Planck, ACT and BLAST data to construct a simple template for the clustered source contribution to the angular power spectrum, useful for extracting small-scale CMB anisotropy measurements from foreground-dominated maps. I will then discuss the challenges associated with extracting physical properties (e.g., host halo mass, redshift distribution, dust temperature) of unresolved DSFGs from the angular power spectrum, and how combining different statistics from Planck, Herschel and future data sets can overcome these issues.
