Optimal Cosmic Microwave Background Lensing Reconstruction and Parameter Estimation with SPTpol Data
Optimal Cosmic Microwave Background Lensing Reconstruction and Parameter Estimation with SPTpol Data
Abstract We perform the first simultaneous Bayesian parameter inference and optimal reconstruction of the gravitational lensing of the cosmic microwave background (CMB), using 100 deg 2 of polarization observations from the SPTpol receiver on the South Pole Telescope. These data reach noise levels as low as 5.8 μ K arcmin …
