Constraints on amplitudes of curvature perturbations from primordial black holes
Edgar Bugaev, Peter Klimai
We calculate the primordial black hole (PBH) mass spectrum produced from a collapse of the primordial density fluctuations in the early Universe using, as an input, several theoret…
Searching for Very-High-Energy Gamma-Ray Bursts from Evaporating Primordial Black Holes
V. B. Petkov, E. V. Bugaev, P. A. Klimai +10
Temporal and energy characteristics of the very-high-energy gamma-ray bursts from evaporating primordial black holes have been calculated by assuming that the photospheric and chro…
Large curvature perturbations near horizon crossing in single-field inflation models
Edgar Bugaev, Peter Klimai
We consider the examples of single-field inflation models predicting large amplitudes of the curvature perturbation power spectrum at relatively small scales. It is shown that in m…
Constraints on the Number Density of Evaporating Primordial Black Holes for the Chromospheric Evaporation Models
V. B. Petkov, E. V. Bugaev, P. A. Klimai +1
Cosmic gamma-ray bursts with primary-photon energies > 10 GeV are sought in the data from the Andyrchy array obtained in the mode of detection of a single cosmic-ray component duri…
