Fine structure in the gamma-ray sky and the origin of UHECR
A. D. Erlykin, A. W. Wolfendale
The EGRET results for gamma ray intensities in and near the Galactic Plane have been analysed in some detail. Attention has been concentrated on energies above 1 GeV and the indivi…
A Magnetic Alpha-Omega Dynamo in Active Galactic Nuclei Disks: II. Magnetic Field Generation, Theories and Simulations
Vladimir I. Pariev, Stirling A. Colgate, John M. Finn
It is shown that a dynamo can operate in an Active Galactic Nuclei accretion disk due to the Keplerian shear and due to the helical motions of expanding and twisting plumes of plas…
A Magnetic Alpha-Omega Dynamo in Active Galactic Nuclei Disks: I. The Hydrodynamics of Star-Disk Collisions and Keplerian Flow
Vladimir I. Pariev, Stirling A. Colgate
A magnetic field dynamo in the inner regions of the accretion disk surrounding the supermassive black holes in AGNs may be the mechanism for the generation of magnetic fields in ga…
Asymmetry Function of Interstellar Scintillations of Pulsars
V. I. Shishov, T. V. Smirnova
A new method for separating intensity variations of a source's radio emission having various physical natures is proposed. The method is based on a joint analysis of the structure…
In-situ acceleration of subrelativistic electrons in the Coma halo and the halo's influence on the Sunyaev-Zeldovich effect
V. A. Dogiel, S. Colafrancesco, C. M. Ko +5
The stochastic acceleration of subrelativistic electrons from a background plasma is studied in order to find a possible explanation of the hard X-ray (HXR) emission detected from…
PAMELA - A Payload for Antimatter Matter Exploration and Light-nuclei Astrophysics
P. Picozza, A. M. Galper, G. Castellini +57
The PAMELA experiment is a satellite-borne apparatus designed to study charged particles in the cosmic radiation with a particular focus on antiparticles. PAMELA is mounted on the…
On the role of the current loss in radio pulsar evolution
V. S. Beskin, E. E. Nokhrina
The aim of this article is to draw attention to the importance of the electric current loss in the energy output of radio pulsars. We remind that even the losses attributed to the…
Slow glitches in the pulsar B1822-09
Tatiana V. Shabanova
The pulsar B1822-09 (J1825-0935) experienced a series of five unusual slow glitches over the 1995-2004 interval. The results of further study of this unusual glitch phenomenon are…
Mechanical Model for Relativistic Blast Waves
A. M. Beloborodov, Z. L. Uhm
Relativistic blast waves can be described by a mechanical model. In this model, the "blast" -- the compressed gas between the forward and reverse shocks -- is viewed as one hot bod…
Fine structure in the gamma-ray sky
A. D. Erlykin, A. W. Wolfendale
The EGRET results for gamma-ray intensities in and near the Galactic Plane have been analysed in some detail. Attention has been concentrated on energies above 1 GeV and the indivi…
Annihilation Emission from the Galactic Black Hole
K. S. Cheng, D. O. Chernyshov, V. A. Dogiel
Both diffuse high energy gamma-rays and an extended electron-positron annihilation line emission have been observed in the Galactic Center (GC) region. Although X-ray observations…
Interstellar Scintillation of PSR J0437-4715
T. V. Smirnova, C. R. Gwinn, V. I. Shishov
We studied the turbulence spectrum of the local interstellar plasma in the direction of PSR J0437-4715, on the basis of our observations and those reported earlier by others. We co…
The unprecedented optical outburst of the quasar 3C 454.3. The WEBT campaign of 2004-2005
M. Villata, C. M. Raiteri, T. J. Balonek
The radio quasar 3C 454.3 underwent an exceptional optical outburst lasting more than 1 year and culminating in spring 2005. The maximum brightness detected was R = 12.0, which rep…
Collapse of Positronium and Vacuum Instability
A. E. Shabad, V. V. Usov
A hypercritical value for the magnetic field is determined, which provides the full compensation of the positronium rest mass by the binding energy in the maximum symmetry state an…
The Anisotropy of Galactic Cosmic Rays as a Product of Stochastic Supernova Explosions
A. D. Erlykin, A. W. Wolfendale
We study the effect of the stochastic character of supernova explosions on the anisotropy of galactic cosmic rays below the knee. We conclude that if the bulk of cosmic rays are pr…
A simple analytical model for dark matter halo structure and adiabatic contraction
E. Vasiliev
A simple analytical model for describing inner parts of dark matter halo is considered. It is assumed that dark matter density is power-law. The model deals with dark matter distri…
Clockwise Stellar Disk and the Dark Mass in the Galactic Center
A. M. Beloborodov, Y. Levin, F. Eisenhauer +4
Two disks of young stars have recently been discovered in the Galactic Center. The disks are rotating in the gravitational field of the central black hole at radii r=0.1-0.3 pc and…
