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…
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…
Detection of an oscillatory phenomenon in optical transient counterpart of GRB090522C from observations on Peak Terskol
B. E. Zhilyaev, M. V. Andreev, A. V. Sergeev +1
22 Sep 2005 Swift-BAT triggered and located GRB050922C. The light curve shows the intense broad peak with of s. The Nordic Optical Telescope has obtained spect…
Photon spectra from final stages of a primordial black hole evaporation in different theoretical models
Edgar Bugaev, Peter Klimai, Valery Petkov
Possibilities of an experimental search for gamma-ray bursts from primordial black hole (PBH) evaporations in space are reconsidered. It is argued that the corresponding constraint…
Mean diurnal variations of cosmic ray intensity as measured by Andyrchi air shower array and Baksan underground scintillation telescope
V. A. Kozyarivsky, A. S. Lidvansky, V. B. Petkov +1
The results of measuring diurnal variations of extensive air showers with energy above 100 TeV detected by the Andyrchi air shower array in 1995-2002 are presented. It is shown tha…
Time Delay of Radiation from Gamma-Ray Burst Sources as a Test for a Model of the Universe
Yu. S. Grishkan, V. B. Petkov, E. G. Vertogradova
The estimation of light velocity dispertion caused by quantum fluctuations influence on electromagnetic wave propogation in four-dimensional space-time is presented. Analytical cos…
