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…
The Energy Spectrum of TeV Gamma-Rays from the Crab Nebula as measured by the HEGRA system of imaging air Cherenkov telescopes
F. Aharonian, The HEGRA Collaboration
The Crab Nebula has been observed by the HEGRA (High-Energy Gamma-Ray Astronomy) stereoscopic system of imaging air Cherenkov telescopes (IACTs) for a total of about 200 hrs during…
