On Recovering the Nonlinear Bias Function from Counts in Cells Measurements
Istvan Szapudi, Jun Pan
We present a simple and accurate method to constrain galaxy bias based on the distribution of counts in cells. The most unique feature of our technique is that it is applicable to…
Angular Clustering with Photometric Redshifts in the Sloan Digital Sky Survey: Bimodality in the Clustering Properties of Galaxies
Tamas Budavari, Andrew J. Connolly, Alexander S. Szalay +18
Understanding the clustering of galaxies has long been a goal of modern observational cosmology. Utilizing our photometric redshift technique a volume limited sample containing mor…
Fast estimation of polarization power spectra using correlation functions
Gayoung Chon, Anthony Challinor, Simon Prunet +2
We present a fast method for estimating the cosmic microwave background polarization power spectra using unbiased estimates of heuristically-weighted correlation functions. This ex…
