Observations of Selected AGN with H.E.S.S
F. Aharonian et al.
A sample of selected active galactic nuclei (AGN) was observed in 2003 and 2004 with the High Energy Stereoscopic System (H.E.S.S.), an array of imaging atmospheric-Cherenkov teles…
Confirmation of strong magnetic field amplification and nuclear cosmic ray acceleration in SN 1006
E. G. Berezhko, L. T. Ksenofontov, H. J. Voelk
It is shown that the nonlinear kinetic model of cosmic ray (CR) acceleration in supernova remnants (SNRs) fits the shell-type nonthermal X-ray morphology, obtained in Chandra obser…
Cosmic ray production in supernova remnants including reacceleration: the secondary to primary ratio
E. G. Berezhko, L. T. Ksenofontov, V. S. Ptuskin +2
We study the production of cosmic rays (CRs) in supernova remnants (SNRs), including the reacceleration of background galactic cosmic rays (GCRs) - thus refining the early consider…
Energetic Particles in Clusters of Galaxies and Starburst Galaxies
H. J. Voelk
The nonthermal characteristics of starburst galaxies and galaxy clusters are reviewed and the perspectives for their observation in high energy gamma rays discussed. It is argued t…
Supernova Remnants: acceleration of particles and gamma-ray emission
H. J. Voelk
Particle acceleration in the dynamically evolving environment of Supernova Remnants is discussed in the framework of a genuinely time-dependent nonlinear theory, assuming spherical…
Particle Acceleration and Gamma-Ray Production in Shell Remnants
H. J. Volk
A number of nearby Northern Hemisphere shell-type Supernova Remnants (SNRs) has been observed in TeV gamma rays, but none of them could be detected so far. This failure calls for a…
