May Heavy neutrinos solve underground and cosmic ray puzzles?
K. Belotsky, D. Fargion, M. Khlopov +1
Primordial Heavy neutrinos of 4th generation might explain different astrophysical puzzles: indeed the simplest 4th neutrino scenario may be still consistent with known 4th neutrin…
Gravitino production by primordial black hole evaporation and constraints on the inhomogeneity of the early Universe
M. Yu Khlopov, A. Barrau, J. Grain
In supergravity models, the evaporation of light Primordial Black Holes (PBHs) should be a source of gravitinos. By considering this process, new stringent limits are derived on th…
Primordial Structure of Massive Black Hole Clusters
Maxim. Yu. Khlopov, Sergei. G. Rubin, Alexander. S. Sakharov
We describe a mechanism of the primordial black holes formation that can explain the existence of a population of supermassive black holes in galactic bulges. The mechanism is base…
