Magnetic Fields of Nearby Active Galactic Nuclei and Correlation of the Highest-Energy Cosmic Rays with their Positions

M. Yu. Piotrovich, Yu. N. Gnedin, T. M. Natsvlishvili

The correlation between the pointing direction of ultra high energy cosmic rays and AGN observed by the Pierre Auger Collaboration is explained in the framework of acceleration pro…

Photon-Axion-Like Particle Coupling Constant and Cosmological Observations

M. Yu. Piotrovich, Yu. N. Gnedin, T. M. Natsvlishvili

We estimated the photon-pseudoscalar particle mixing constant from the effect of cosmological alignment and cosmological rotation of polarization plane of distant QSOs. This effect…

Synchrotron Self-Absorption Process in GRBs and the Isotropic Energy - Peak Energy Fundamental Relation

M. Yu. Piotrovich, Yu. N. Gnedin, T. M. Natsvlishvili

The existence of strong correlation between the peak luminosity (and/or bolometric energetics) of Gamma Ray Bursts (GRB) is one of the most intrigue problem of GRB physics. This co…

Polarization from a Strongly Magnetized Accretion Disks: Asymptotic Wavelength Behaviour

Yu. N. Gnedin, N. A. Silant'ev, P. S. Shternin

We calculate the polarization of radiation from thick accretion disks with vertically averaged global magnetic field. The polarization arises as a result of the radiation scatterin…

Collimated high-energy photons and others possible observational effects of the photon angular and spectral distribution in gamma-ray bursts sources

V. V. Sokolov, V. G. Kurt, G. S. Bisnovatyi-Kogan +4

Typical observational gamma-ray burst (GRB) spectra are discussed and, in this connection, what is the origin of the compactness problem and how it was solved at first. If the thre…

Spectropolarimetry and Infrared Photometry of Magnetic White Dwarfs: Vacuum Polarization Effect or Magnetic CIA?

Yu. N. Gnedin, N. V. Borisov, V. M. Larionov +3

We present brief review of two probable physical mechanisms that can explain the results of photometric and spectropolarimetric observations of magnetic white dwarfs: vacuum polari…
