Large Covariance Matrices: Smooth Models from the 2-Point Correlation Function

6 Oct 2015 Ross O'Connell Daniel Eisenstein Mariana Vargas Shirley Ho Nikhil Padmanabhan

We introduce a new method for estimating the covariance matrix for the galaxy correlation function in surveys of large-scale structure. Our method combines simple theoretical results with a realistic characterization of the survey to dramatically reduce noise in the covariance matrix... (read more)
