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…
Photons and Particle Production in Cassiopeia A: Predictions from Nonlinear Diffusive Shock Acceleration
Donald C. Ellison, Philippe Goret, Matthew G. Baring +2
We calculate particle spectra and continuum photon emission from the Cassiopeia A supernova remnant (SNR). The particle spectra, ion and electron, result from diffusive shock accel…
Search for >= 400 GeV gamma-rays from the SNR Cas A
P. Goret, C. Gouiffes, E. Nuss +1
The recent detection of a hard X-ray component in the supernova remnant Cassiopeia A is interpreted as synchrotron emission from electrons accelerated to energies up to 40 TeV (All…
Very High Energy Gamma-ray spectral properties of Mrk 501 from CAT Cerenkov telescope observations in 1997
A. Djannati-Atai, F. Piron, A. Barrau +31
The BL Lac object Mrk 501 went into a very high state of activity during 1997, both in VHE gamma-rays and X-rays. We present here results from observations at energies above 250 Ge…
Shock Acceleration and Gamma-Ray Emitting Supernova Remnants
Matthew G. Baring, Donald C. Ellison, Stephen P. Reynolds +2
Diffusive shock acceleration in the environs of a remnant's expanding shell is a popular candidate for the origin of SNR gamma-rays. In this paper, results from our study of non-li…
Performances of the CAT imaging telescope and some preliminary results on Mkn 180 and the Crab
A. Barrau, R. Bazer-Bachi, H. Cabot +33
The CAT imaging telesope, which uses the Atmospheric Cherenkov Technique to observe TeV gamma-ray sources, has been operating since September 1996. Located in southern France, it f…
