The evolution of a supermassive binary caused by an accretion disc
P. B. Ivanov, J. C. B. Papaloizou, A. G. Polnarev
The interaction of a massive binary and a non-self-gravitating circumbinary accretion disc is considered. The shape of the stationary twisted disc produced by the binary is calcula…
The ``angular size - redshift'' relation for compact radio structures in quasars and radio galaxies
L. I. Gurvits, K. I. Kellermann, S. Frey
We discuss the ``angular size - redshift'' relation for compact radio sources distributed over a wide range of redshifts 0.01 < z < 4.73. Our study is based on a sample of 330 5 GH…
Frame dragging and other precessional effects in black hole-pulsar binaries
N. Wex, S. Kopeikin
For radio pulsars in orbit with a compact companion, pulsar timing observations have proved to be a powerful tool for identifying the physical nature of the companion. Unfortunatel…
Plasma Ejection from Magnetic Flares and the X-ray Spectrum of Cygnus X-1
A. M. Beloborodov
The hard X-rays in Cyg X-1 and similar black hole sources are possibly produced in an active corona atop an accretion disk. We suggest that the observed weakness of X-ray reflectio…
Minkowski Functionals and Cluster Analysis for CMB Maps
D. Novikov, Hume A. Feldman, Sergei F. Shandarin
We suggest novel statistics for the CMB maps that are sensitive to non-Gaussian features. These statistics are natural generalizations of the geometrical and topological methods th…
Self-Similar Temporal Behavior of Gamma-Ray Bursts
A. M. Beloborodov, B. E. Stern, R. Svensson
We apply Fourier analysis to 214 light curves of long gamma-ray bursts and study the statistical properties of their power density spectra (PDSs). The averaged PDS is found to foll…
On the self-consistent model of the axisymmetric radio pulsar magnetosphere
V. S. Beskin, L. M. Malyshkin
We consider a model of axisymmetric neutron star magnetosphere. In our approach, the current density in the region of open field lines is constant and the returning current flows i…
Line Emission from an Accretion Disk around a Black hole: Effects of Disk Structure
Vladimir I. Pariev, Benjamin C. Bromley
The observed iron K-alpha fluorescence lines in Seyfert-1 galaxies provide strong evidence for an accretion disk near a supermassive black hole as a source of the line emission. Th…
Classification of singular points in polarization field of CMB and eigenvectors of Stokes matrix
A. D. Dolgov, A. G. Doroshkevich, D. I. Novikov +1
Analysis of the singularities of the polarization field of CMB, where polarization is equal to zero, is presented. It is found that the classification of the singular points differ…
Super-Eddington accretion disc around a Kerr black hole
Andrei M. Beloborodov
We calculate the structure of accretion disc around a rapidly rotating black hole with a super-Eddington accretion rate. The luminosity and height of the disc are reduced by the ad…
Polarization change due to fast winds from accretion disks
Andrei M. Beloborodov
A fraction of the radiation produced by an accretion disk may be Thomson scattered by a wind flowing away from the disk. Employing a simple plane-parallel model of the wind, we cal…
Small-scale structure of dark matter and microlensing
A. V. Gurevich, K. P. Zybin, V. A. Sirota
It has been revealed using microlensing that a considerable part, possibly more than half, of the dark matter in the halo of our Galaxy consists of objects with a mass spectrum ran…
General Statistical properties of the CMB Polarization field
P. D. Naselsky, D. I. Novikov
The distribution of the polarization of the Cosmic Microwave Background (CMB) in the sky is determined by the hypothesis of random Gaussian distribution of the primordial density p…
Scattering of X-ray emission lines by a helium atom
L. Vainshtein, R. Sunyaev, E. Churazov
The differential cross section for scattering of the astrophysically important X-ray emission lines by a helium atom is calculated with an accuracy sufficient for astrophysical app…
