Lensing Simulation and Power Spectrum Estimation for High Resolution CMB Polarization Maps

Cosmology and Nongalactic Astrophysics 2013-11-14 v1

Abstract

We present efficient algorithms for CMB lensing simulation and power spectrum es- timation for flat-sky CMB polarization maps. We build a pure B-mode estimator to remedy E to B leakage due to partial sky coverage. We show that our estimators are unbiased, and consistent with the projected errors. We demonstrate our algorithm using simulated observations of small sky patches with realistic noise and weights for upcoming CMB polarization experiments.
