The Origin of the Magnetic Fields of the Universe: The Plasma Astrophysics of the Free Energy of the Universe
S. A. Colgate, H. Li, V. Pariev
(abridged) The interpretation of Faraday rotation measure maps of AGNs within galaxy clusters has revealed regions, kpc, that are populated with large, G…
Current Status of cosmological models with mixed dark matter
E. V. Mikheeva
An analysis of cosmological mixed dark matter models in spatially flat Friedmann Universe with zero -term is presented. We argue that the introduction of cosmic gravity waves he…
-Inflation and CMBR Anisotropy
Vladimir N. Lukash
We argue that a -inflation model can ensure large relative contribution of cosmic gravity waves into the at COBE scale preserving at the same time a near scale-invariant…
Cosmological models: theory and observations
V. N. Lukash
The current status of the theoretical and observational cosmology is reviewed.
Estimation of relativistic accretion disk parameters from iron line emission
Vladimir I. Pariev, Benjamin C. Bromley, Warner A. Miller
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 emission. Here we…
Gravitational waves, baryogenesis, and dark matter from primordial black holes
A. D. Dolgov, P. D. Naselsky, I. D. Novikov
We discuss the hypothesis that the cosmological baryon asymmetry and entropy were produced in the early Universe by the primordial black hole (PBHs) evaporation.
An Off-line Scan of the BATSE Daily Records and a Large Uniform Sample of Gamma-Ray Bursts
Boris E. Stern, Yana Tikhomirova, Dmitrii Kompaneets +2
During a scan of the archival BATSE daily records covering the entire 9.1 years (TJD 8369-11690) of the BATSE operation, 3906 gamma-ray bursts (GRBs) have been detected. 2068 of th…
VSOP observation of the quasar PKS 2215+020: a new laboratory for core-jet physics at z=3.572
A. P. Lobanov, L. I. Gurvits, S. Frey +4
We report results of a VSOP (VLBI Space Observatory Programme) observation of a high redshift quasar PKS 2215+020 (z=3.572). The ~1 milliarcsecond resolution image of the quasar re…
Amplitude-Phase Analysis of Cosmic Microwave Background maps
P. Naselsky, D. Novikov, Joseph Silk
We propose a novel method for the extraction of unresolved point sources from CMB maps. This method is based on the analysis of the phase distribution of the Fourier components for…
Space-VLBI observations of OH maser OH34.26+0.15: low interstellar scattering
V. I. Slysh, M. A. Voronkov, V. Migenes +16
We report on the first space-VLBI observations of the OH34.26+0.15 maser in two main line OH transitions at 1665 and 1667 MHz. The observations involved the space radiotelescope on…
Bizarre Hard X-ray Outbursts of Cygnus X-1
Boris E. Stern, Andrei M. Beloborodov, Juri Poutanen
A very high activity of Cygnus X-1 on 1999 April 19-21 was recorded by BATSE Large Area Detectors onboard the Compton Gamma-Ray Observatory. The peak luminosity was one order of ma…
On the Internal Structure of Relativistic Jets
Vassily S. Beskin, Leonid Malyshkin
A magnetohydrodynamic model is constructed for a cylindrical jet immersed in an external uniform magnetic field. It is shown that, as in the force-free case, the total electric cur…
Free-fall accretion and emitting caustics in wind-fed X-ray sources
Andrei F. Illarionov, Andrei M. Beloborodov
In wind-fed X-ray binaries the accreting matter is Compton cooled and falls freely onto the compact object. The matter has a modest angular momentum and accretion is quasi-sphe…
Small-scale inviscid accretion discs around black holes
Andrei M. Beloborodov, Andrei F. Illarionov
Gas falling quasi-spherically onto a black hole forms an inner accretion disc if its specific angular momentum exceeds $\lmin\sim r_gc$ where is the Schwarzschild radius.…
On non-Gaussianity in the Cosmic Microwave Background
Dmitri Novikov, Jens Schmalzing, Viatcheslav F. Mukhanov
We consider a cosmological model with non-Gaussian initial perturbations, which in principle could be generated in non-standard inflationary scenarios with two or more scalar field…
Generalised inflation with a gravitational wave background
V. N. Lukash, E. V. Mikheeva, V. Muller +1
We propose a Lambda-inflation model which explains a significant part of the COBE signal by primordial cosmic gravitational waves. The primordial density perturbations fulfill both…
A new model of a tidally disrupted star
P. B. Ivanov, I. D. Novikov
A new semi-analytical model of a star evolving in a tidal field is proposed. The model is a generalization of the so-called 'affine' stellar model. In our model the star is compose…
On the Efficiency of Internal Shocks in Gamma-Ray Bursts
Andrei M. Beloborodov
The fraction of a fireball kinetic kinetic energy that can be radiated away by internal shocks is sensitive to the amplitude of initial fluctuations in the fireball. We give a simp…
Grad-Shafranov equation with anisotropic pressure
V. S. Beskin, I. V. Kuznetsova
The most general form of the nonrelativistic Grad-Shafranov equation describing anisotropic pressure effects is formulated within the double adiabatic approximation. It gives a pos…
Fine Structure in the Energy Spectrum of Cosmic Ray Protons at 50 GeV ?
A. D. Erlykin, S. J. Fatemi, A. W. Wolfendale
The recently published precise spectrum of cosmic ray protons from the Alpha Magnetic Spectrometer has been examined in some detail from the standpoint of a search for deviations f…
Non-pulsed emission from the binary system PSR B1259-63
Maria A. Chernyakova, Andrei F. Illarionov
PSR B1259-63 is the only known binary system with a radio pulsar from which the non-pulsed radio and X-ray emission was detected. The companion star in this system is a Be star SS…

A generalized inflation model with cosmic gravitational waves
V. N. Lukash, E. V. Mikheeva, V. Müller +1
