Extreme-Value Distributions and Primordial Black-Hole Formation

  title={Extreme-Value Distributions and Primordial Black-Hole Formation},
  author={Florian Kuhnel and Dominik J. Schwarz},
We argue that primordial black-hole formation must be described by means of extreme-value theory. This is a consequence of the large values of the energy density required to initiate the collapse of black holes in the early Universe and the finite duration of their collapse. Compared to the Gaußian description of the most extreme primordial density fluctuations, the holes’ mass function is narrower and peaks towards larger masses. Secondly, thanks to the shallower fall-off of extremevalue…

Non-perturbative non-Gaussianity and primordial black holes

We present a non-perturbative method for calculating the abundance of primordial black holes given an arbitrary one-point probability distribution function for the primordial curvature perturbation,
