Measurement of the Cherenkov light spectrum and of the polarization with the HEGRA-IACT-system
M. Doering, K. Bernloehr, G. Hermann +2
The HEGRA system of Imaging Atmospheric Cherenkov Telescopes (IACTs) detects Cherenkov light produced by air showers. The concept of stereoscopic observation with the five HEGRA te…
Study of the photon flux from the night sky at La Palma and Namibia, in the wavelength region relevant for imaging atmospheric Cherenkov telescopes
S. Preuss, G. Hermann, W. Hofmann +1
The level of the night sky background light at La Palma and Namibia was determined, with emphasis on the wavelength region and solid angle coverage relevant for the operation of im…
A study of Tycho's SNR at TeV energies with the HEGRA CT-System
F. A. Aharonian, A. G. Akhperjanian, J. A. Barrio +1
Tycho's supernova remnant (SNR) was observed during 1997 and 1998 with the HEGRA Cherenkov Telescope System in a search for gamma-ray emission at energies above ~1 TeV. An analysis…
Evidence for TeV gamma ray emission from Cassiopeia A
HEGRA Collaboration, F. Aharonian
232 hours of data were accumulated from 1997 to 1999, using the HEGRA Stereoscopic Cherenkov Telescope System to observe the supernova remnant Cassiopeia A. TeV gamma ray emission…
