The time averaged TeV energy spectrum of Mkn 501 of the extraordinary 1997 outburst as measured with the stereoscopic Cherenkov telescope system of HEGRA
F. Aharonian
During the several months of the outburst of Mkn 501 in 1997 the source has been monitored in TeV gamma-rays with the HEGRA stereoscopic system of imaging atmospheric Cherenkov tel…
TeV Gamma-ray Observations of the Crab and Mkn 501 during Moonshine and Twilight
D. Kranich, R. Mirzoyan, D. Petry +1
TeV Gamma-ray signals from the Crab Nebula and Mkn 501 were detected with the HEGRA CT1 imaging Cerenkov telescope during periods when the moon was shining and during twilight. Thi…
The Cosmic Ray Proton Spectrum determined with the Imaging Atmospheric Cherenkov-Technique
F. Aharonian
The HEGRA system of 4 Imaging Atmospheric Cherenkov Telescopes (IACTs) has been used to determine the flux and the spectrum of cosmic ray protons over a limited energy range around…
The Electronics of the H1 Lead/Scintillating-Fibre Calorimeters
H1 SpaCal Group, R. -D. Appuhn et al
The electronic system developed for the SpaCal lead/scintillating-fibre calorimeters of the H1 detector in operation at the HERA ep collider is described in detail and the performa…
The time structure of Cherenkov images generated by TeV gamma-rays and by cosmic rays
HEGRA Collaboration, M. Hess et al
The time profiles of Cherenkov images of cosmic-ray showers and of gamma-ray showers are investigated, using data gathered with the HEGRA system of imaging atmospheric Cherenkov te…
Search for gamma-ray bursts above 20 TeV with the HEGRA AIROBICC Cherenkov array
HEGRA collaboration, L. Padilla, B. Funk +34
A search for gamma-ray bursts (GRBs) above 20 TeV within the field of view (1 sr) of the HEGRA AIROBICC Cherenkov array (29N, 18W, 2200 m a.s.l.) has been performed using data take…
Recent Observations of gamma-rays above 1.5 TeV from Mkn 501 with the HEGRA 5 m^2 Air Cherenkov Telescope
D. Kranich, T. Deckers, E. Lorenz +3
Since February 1997 the BL Lac object Mkn 501 is in a ``high state'' of gamma-ray emission. The HEGRA collaboration has studied Mkn 501 with their air Cherenkov telescopes on La Pa…
Detection of VHE Gamma-rays from Mkn 421 with the HEGRA Cherenkov Telescopes
D. Petry, S. M. Bradbury, A. Konopelko +1
A detection of Gamma-rays from Mkn 421 at energies above 1 TeV is reported, based on observations made in December 1994 - May 1995 with the first two HEGRA Cherenkov telescopes. >F…
