Description
Unambiguously detecting the primordial gravitational waves signal requires precise subtraction of confounding foregrounds, which have much larger amplitude. One such foreground is B-modes generated by gravitational lensing of E-modes.
We validated an optimal map-based delensing pipeline on simulations, with different complexities of noise including white and 1/f noise, homogeneous and inhomogeneous sky coverage, and realistic foregrounds emissions. We compare the delensing pipeline at map-level and at power spectra level.
