Description
We discuss the impact of non-linear matter clustering and post-Born lensing corrections to CMB lensing reconstruction for next generation surveys. In particular, we will explore the impact of non-Gaussian deflections on Maximum a Posteriori lensing estimators, which are able to provide optimal measurements of the lensing field, in contrast to quadratic estimators. Finally, we will discuss potential ways of mitigating biases.
