Geomagnetic Effects on the Performance of Atmospheric Cerenkov Telescopes
P. M. Chadwick, K. Lyons, T. J. L. McComb +5
Atmospheric Cerenkov telescopes are used to detect electromagnetic showers from primary gamma rays of energy > 300 GeV and to discriminate these from cascades due to hadrons using…
The energy spectra of TeV sources measured with the Durham Mark 6 Telescope
P. M. Chadwick, K. Lyons, T. J. L. McComb +5
A programme of detailed simulations of the response of the Durham Mark 6 atmospheric Cherenkov telescope is in progress. The effective collecting area for triggering by gamma-ray s…
TeV Gamma Ray Emission from Cen X-3
P. M. Chadwick, K. Lyons, T. J. L. McComb +5
Cen X-3 is a well-studied high-mass accreting X-ray binary and a variable source of high energy gamma rays from 100 MeV to 1 TeV. The object has been extensively monitored with the…
Measurements of Flux Limits for TeV Emission from AGNs
P. M. Chadwick, K. Lyons, T. J. L. McComb +6
The University of Durham Mark 6 Telescope has been used to make observations of a number of AGNs visible from the Southern Hemisphere. Results are presented for limits to VHE gamma…
Correlation between the X-ray and TeV Gamma Ray Emission from an Accreting X-ray Binary
P. M. Chadwick, K. Lyons, T. J. L. McComb +6
This paper has been withdrawn by the authors.
Measurement of sky clarity using FIR radiometers as an adjunct to atmospheric Cerenkov radiation measurements
D. J. Buckley, M. C. Dorrington, P. J. Edwards +3
A technique for detecting the presence of cloud in the field of view of an atmospheric Cerenkov telescope using a far infra red radiometer is described. Models for the radiative em…
