On the Problem of the Super Reason in Astrophysics

The Giant Silence of the Universe or the absence of "Space Miracles" is in obvious contradiction with the rapid evolution of our civilization. The most striking fact is that both these phenomena, if taken sepa...

The Death of Compact Binary Stars

Merging rates for compact binaries (double neutron stars or black holes) are calculated based on modern concepts of binary star evolution. It is found that the first laser interferometers, with rms sensitiviti...

Tests for coalescing binary neutron stars as cosmological origin of gamma-ray bursts

Theoretical logN-logS distributions and (V/V _max) tests of gamma-ray bursts in the model of coalescence of neutron star (NS+NS) and/or NS+black hole (NS+BH) binaries are calculated for a flat Universe (Ω=1) with ...
