Using inpainting to construct accurate cut-sky CMB estimators
(American Physical SocietyPhysical Review D - Particles, Fields, Gravitation and Cosmology, 2017-02-23)
The direct evaluation of manifestly optimal, cut-sky cosmic microwave background (CMB) power spectrum and bispectrum estimators is numerically very costly, due to the presence of inverse-covariance filtering operations. ...
