Very High Energy gamma-ray observations of Mrk 501 using TACTIC imaging gamma-ray telescope during 2005-06
S. V. Godambe, R. C. Rannot, P. Chandra +16
In this paper we report on the Markarian 501 results obtained during our TeV -ray observations from March 11 to May 12, 2005 and February 28 to May 7, 2006 for 112.5 hours with…
The TACTIC atmospheric Cherenkov Imaging telescope
R. Koul, A. K. Tickoo, S. K. Kaul +19
The TACTIC -ray telescope, equipped with a light collector of area 9.5m and a medium resolution imaging camera of 349-pixels, has been in operation at Mt.Abu, India si…
Very High Energy -ray and Near Infrared observations of 1ES2344+514 during 2004-05
S. V. Godambe, R. C. Rannot, K. S. Baliyan +20
We have observed the BL Lac object 1ES2344+514 (z = 0.044) in Very High Energy (VHE) gamma-ray and near-infrared wavelength bands with TACTIC and MIRO telescopes respectively. The…
Observations of TeV gamma-rays from Mrk 421 during Dec. 2005 to Apr. 2006 with the TACTIC telescope
K. K. Yadav, P. Chandra, A. K. Tickoo +16
The TACTIC -ray telescope has observed Mrk 421 on 66 clear nights from Dec. 07, 2005 to Apr. 30, 2006, totalling 202 hours of on-source observations. Here, we report the…
Mrk 421, Mrk 501, and 1ES 1426+428 at 100 GeV with the CELESTE Cherenkov Telescope
D. A. Smith, E. Brion, R. Britto +18
We have measured the gamma-ray fluxes of the blazars Mrk 421 and Mrk 501 in the energy range between 50 and 350 GeV (1.2 to 8.3 x 10^25 Hz). The detector, called CELESTE, used firs…
Measurement of the Crab Flux Above 60 GeV with the CELESTE Cherenkov Telescope
M. De Naurois, J. Holder, R. Bazer-Bachi +29
We have converted the former solar electrical plant THEMIS (French Pyrenees) into an atmospheric Cherenkov detector called CELESTE, which records gamma rays above 30 GeV (7E24 Hz).…
