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)…

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…

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…

A search for TeV gamma-ray emission from SNRs, pulsars and unidentified GeV sources in the Galactic plane in the longitude range between -2 deg and 85 deg

HEGRA-Collaboration, F. A. Aharonian

Using the HEGRA system of imaging atmospheric Cherenkov telescopes, one quarter of the Galactic plane (-2 deg < l < 85 deg) was surveyed for TeV gamma-ray emission from point sourc…
