Magnetic field behaviour in a spherically-symmetric accretion flow for parameters typical of
single black holes in the Galaxy is discussed. It is shown that in the majority of Galaxy …

Multicolor panoramic photometer-polarimeter (MPPP) with a time resolution of 1μs has been
built based on a position-sensitive detector (PSD) and used at the 6-m telescope in SAO …

A hardware and software complex of the MANIA experiment designed to search for and
study the photometric variability of astrophysical objects with a temporal resolution of 10− 6 s …

We consider the gravitational magnification of light for binary systems containing two
compact objects: white dwarfs, a white dwarf and a neutron star or a white dwarf and a black …

We have developed a method for analyzing the kinematic association of isolated relativistic
objects-possible remnants of disrupted close binary systems. We investigate pairs of fairly …

In the great majority of the cases, present astronomical observations are realized analyzing
only first order spatial or temporal coherence properties of the collected photon stream …

A facility for the registration of light fluxes meant for the study of their properties with high
temporal resolution is described. The “Quantochron 4-48” acquisition facility measures the …

A general upper bound is derived on the total energy in incoherent nonthermal transients at
frequency ν from relativistic fireballs with bulk Lorentz factors Γ and observed duration Δ t …

General properties of accretion onto isolated stellar-mass black holes in the Galaxy are
discussed. An analysis of plasma internal energy growth during the infall is performed …

The set of equipment and software of MANIA experiment for search for and study of
astrophysical objects variability with time resolution of 1 us is described. Observations are …
