An iterative CMB lensing estimator minimizing instrumental noise bias
Louis Legrand, Blake Sherwin, Anthony Challinor +2
Noise maps from CMB experiments are generally statistically anisotropic, due to scanning strategies, atmospheric conditions, or instrumental effects. Any mis-modeling of this compl…
Characterizing CMB noise anisotropies from CMB delensing
Louis Legrand, Julien Carron
Un-doing the effect of gravitational lensing on the Cosmic Microwave Background (`de-lensing') is essential in shaping constraints on weak signals limited by lensing effects on the…
On likelihood-based analysis of the gravitationally (de)lensed CMB
Julien Carron
By reducing variance induced by gravitational lensing, likelihood-based de-lensing techniques have true potential to extract significantly more information from deep and high-resol…
CMB-S4: Foreground-Cleaning Pipeline Comparison for Measuring Primordial Gravitational Waves
Federico Bianchini, Dominic Beck, W. L. Kimmy Wu +6
We compare multiple foreground-cleaning pipelines for estimating the tensor-to-scalar ratio, , using simulated maps of the planned CMB-S4 experiment within the context of the So…
Detecting rotation from lensing in the CMB
Julien Carron, Enea di Dio, Ruth Durrer
An excellent estimate of the lensing signal is expected from the availability of deep and high-resolution polarization data in the near future. This is most important to allow for…
