Reanalysis of the high energy cutoff of the 1997 Mkn 501 TeV energy spectrum
HEGRA Collaboration, F. Aharonian
Data taken with the HEGRA system of imaging atmospheric Cherenkov telescopes during the 1997 flares of Mkn 501 are reanalyzed using an algorithm providing improved energy resolutio…
The TeV Energy Spectrum of Mkn 501 Measured with the Stereoscopic Telescope System of HEGRA during 1998 and 1999
The HEGRA Collaboration, F. Aharonian, A. Akhperjanian +1
During 1997, the BL Lac object Mkn 501 went into an extraordinary state of high X-ray and TeV gamma-ray activity, lasting more than 6 months. In this paper we report on the TeV emi…
Rejection of the hypothesis that Markarian 501 TeV photons are pure Bose-Einstein condensates
The HEGRA Collaboration, F. Aharonian, A. Akhperjanian +1
The energy spectrum of the Blazar type galaxy Markarian 501 (Mrk 501) as measured by the High-Energy-Gamma-Ray Astronomy (HEGRA) air Cerenkov telescopes extends beyond 16 TeV and c…
Observations of the supernova remnant W28 at TeV energies
G. P. Rowell, T. Naito, S. A. Dazeley +24
The atmospheric Cerenkov imaging technique has been used to search for point-like and diffuse TeV gamma-ray emission from the southern supernova remnant, W28, and surrounding regio…
Very High-Energy Gamma-Ray Observations of PSR B1509-58 with the CANGAROO 3.8m Telescope
T. Sako, Y. Matsubara, Y. Muraki +31
The gamma-ray pulsar PSR B1509-58 and its surrounding nebulae have been observed with the CANGAROO 3.8m imaging atmospheric Cherenkov telescope. The observations were performed fro…
