Search for a TeV gamma-ray halo of Mkn 501

HEGRA Collaboration, F. Aharonian

For distant extragalactic sources of gamma-rays in the PeV energy range, interactions of the gamma rays with intergalactic diffuse radiation fields will initiate a pair cascade. De…

Optimizing the angular resolution of the HEGRA telescope system to study the emission region of VHE gamma rays in the Crab Nebula

HEGRA Collaboration, F. Aharonian

The HEGRA system of imaging atmospheric Cherenkov telescopes provides for specially selected classes of events an angular resolution of better than 3'. By comparing the measured an…

Constraints on the Cosmic Infra-Red Background based on BeppoSAX and CAT spectra of Mkn 501

J. Guy, C. Renault, F. A. Aharonian +2

The TeV and X-ray data obtained by the imaging Cherenkov telescope CAT and X-ray satellite BeppoSAX during the remarkable flare of Mkn 501 in April 16, 1997 are used to constrain t…

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…
