Real space CMB lensing reconstruction with point source masks

Carvalho, C. Sofia; Tereno, Ismael

An incomplete sky coverage poses difficulties in the extraction of the weak lensing information from the CMB. We test the reconstruction of the weak lensing convergence from CMB maps to which masks of point sources have been applied. We use the quadratic estimator with a kernel with finite support acting in real space for a Planck simulation. We r…
