Title: Analytic power spectrum covariance & How to characterize ultrahigh energy cosmic ray sources without really identifying them
Description: Jay Wadekar: Power spectrum (a measure of two-point clustering) of galaxies from surveys is crucial to constrain cosmological parameters. A robust model for covariance of power spectrum is essential for the constraints. Expensive mock simulations are traditionally used to compute the covariance matrix (a process which takes months). We show that the covariance matrix can be calculated analytically (within minutes), which is in good agreement with the state-of-the-art mock simulations. We include the highly non-trivial galaxy survey mask, redshift space distortions, non-linear evolution, shot noise and galaxy bias in our analytic method. Marco Muzio: How to characterize ultrahigh energy cosmic ray sources without really identifying them (12:30 PM - 1:30 PM, 726 Broadway, 940, CCPP Seminar)
