High-Energy Neutrino Production through Photopion Processes in Blazars
C. D. Dermer, A. Atoyan
The measured spectral energy distribution and variability time scale are used to determine the radiation and magnetic-field energy densities in the relativistic plasma that forms t…
Broad-band diffuse gamma ray emission of the Galactic Disk
F. A. Aharonian, A. M. Atoyan
The contributions of different radiation mechanisms to the diffuse gamma-ray emission of the galactic disk are studied in a broad energy region from X-rays to very high energy gamm…
On energy-dependent propagation effects and acceleration sites of relativistic electrons in Cassiopeia A
A. M. Atoyan, R. J. Tuffs, F. A. Aharonian +1
We consider the effect of energy dependent propagation of relativistic electrons in a spatially inhomogeneous medium in order to interpret the broad-band nonthermal radiation of th…
On the gamma-ray fluxes expected from Cassiopeia A
A. M. Atoyan, F. A. Aharonian, R. J. Tuffs +1
Based on the results of our previous study of the broad band synchrotron emission of Cas A in the framework of a spatial inhomogeneous model, we calculate the fluxes of gamma-radia…
Radio spectrum of the Crab nebula as an evidence for fast initial spin of its pulsar
A. M. Atoyan
The origin of relativistic electrons in the Crab nebula which are producing the broad-band flat radio spectrum of this prototype plerion has proved difficult to understand. Here I…
Nonthermal Radiation of the Crab Nebula
F. A. Aharonian, A. M. Atoyan
The radiation mechanisms contributing to formation of the nonthermal spectrum of the Crab Nebula, as well as the information that could be derived from future observations in diffe…
