Why the Universal Threshold for Primordial Black Hole Formation is Universal (2405.05208v1)
Published 8 May 2024 in astro-ph.CO and gr-qc
Abstract: We show why the threshold for primordial black hole formation is universal (independent from the shape of the perturbation) when expressed in terms of the volume averaged compaction function. The proof is rooted in the self-similarity of the gravitational collapse phenomenon at criticality.
