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 significantly5 p.application/pdfengcc-by-nc-nd (c) Cid, 2019http://creativecommons.org/licenses/by-nc-nd/3.0/es/Forats negres (Astronomia)Pertorbació (Astronomia)Treballs de fi de grauBlack holes (Astronomy)Perturbation (Astronomy)Bachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
