In this work we study the formation of primordial black holes, through the collapse of spherically symmetric overdensities during the radiation era. We study the effect of departures from Gaussianity of the primordial curvature perturbations in the threshold for collapse of high peaks. We find that non-Gaussianity can affect the probability of black hole formation significantly
