A possible use for polarizers in imaging atmospheric Cherenkov telescopes
I. de la Calle, J. L. Contreras, J. Cortina +1
Cherenkov radiation produced in Extensive Air Showers shows a net polarization. This article discusses its properties and physical origin, and proposes an arrangement of polarizers…
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…
