How well do we know the primordial black hole abundance: The crucial role of nonlinearities when approaching the horizon
We discuss the nonlinear corrections entering in the calculation of the primordial black hole abundance from the nonlinear radiation transfer function and the determination of the true physical horizon crossing. We show that the current standard techniques to calculate the abundance of primordial bl...
