Gamma-Ray Astronomy of Cosmic Rays
Heinrich Voelk
Many of the basic problems in the astrophysics of charged Cosmic Rays remain on principle unresolved by in situ observations in the Solar System due to the chaotic nature of the pr…
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…
On the FIR emission from intracluster dust
Cristina C. Popescu, Richard J. Tuffs, Joerg Fischera +1
We make predictions for the diffuse far-infrared (FIR) emission from dust in the intracluster medium (ICM) of the Virgo cluster using detailed information on potential dust sources…
The gamma-ray visibility of supernova remnants: a test of cosmic ray origin
L O'C Drury, F A Aharonian, H J Voelk
Gamma ray production in supernova remnants is discussed on the basis of current ideas about cosmic ray acceleration.
