The unidentified TeV source (TeVJ2032+4130) and surrounding field: Final HEGRA IACT-System results
HEGRA Collaboration, F. Aharonian
The unidentified TeV source in Cygnus is now confirmed by follow-up observations from 2002 with the HEGRA stereoscopic system of Cherenkov Telescopes. Using all data (1999 to 2002)…
The Crab Nebula and Pulsar between 500 GeV and 80 TeV: Observations with the HEGRA stereoscopic air Cherenkov telescopes
F. Aharonian et al.
The Crab supernova remnant has been observed regularly with the stereoscopic system of 5 imaging air Cherenkov telescopes that was part of the High Energy Gamma Ray Astronomy (HEGR…
Observations of 54 Active Galactic Nuclei with the HEGRA System of Cherenkov Telescopes
The HEGRA Collaboration, F. Aharonian, A. Akhperjanian +1
A sample of 54 selected Active Galactic Nuclei (AGN) has been observed with the HEGRA stereoscopic system of Cherenkov Telescopes between 1996 and 2002 in the TeV energy regime. Th…
Coordinated Multiwavelength Observations of BL Lacertae in 2000
M. Boettcher
BL Lacertae was the target of an extensive multiwavelength monitoring campaign in the second half of 2000. Simultaneous or quasi-simultaneous observations were taken at radio (UMRA…
The Technical Performance of the HEGRA System of Imaging Air Cherenkov Telescopes
G. Puehlhofer, O. Bolz, N. Goetting +1
Between early 1997 and late 2002, the HEGRA collaboration operated a stereoscopic system of 4 (later 5) imaging atmospheric Cherenkov telescopes. In this paper we present the calib…
Is the Giant Radio Galaxy M87 a TeV Gamma-Ray Emitter?
HEGRA Collaboration, F. Aharonian, A. Akhperjanian +1
For the first time an excess of photons above an energy threshold of 730 GeV from the giant radio galaxy M87 has been measured at a significance level above 4 sigma. The data have…
