Godambe, S. V., Rannot, R. C., Chandra, P., Yadav, K. K., Tickoo, A. K., Venugopal, K., ...

In this paper we report on the Markarian 501 results obtained during our TeV $\gamma$-ray observations from March 11 to May 12, 2005 and February 28 to May 7, 2006 for 112.5 hours with the TACTIC...

The TACTIC atmospheric Cherenkov Imaging telescope (2007)

Koul, R., Tickoo, A. K., Kaul, S. K., Kaul, S. R., Kumar, N., Yadav, K. K., ...

The TACTIC $\gamma$-ray telescope, equipped with a light collector of area $\sim$9.5m$^2$ and a medium resolution imaging camera of 349-pixels, has been in operation at Mt.Abu, India since 2001. This...

Very High Energy $\gamma$-ray and Near Infrared observations of 1ES2344+514 during 2004-05 (2007)

Godambe, S. V., Rannot, R. C., Baliyan, K. S., Tickoo, A. K., Thoudam, S., Dhar, V. K., ...

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 were...

Observations of TeV gamma-rays from Mrk 421 during Dec. 2005 to Apr. 2006 with the TACTIC telescope (2007)

Yadav, K. K., Chandra, P., Tickoo, A. K., Rannot, R. C., Godambe, S., Koul, M. K., ...

The TACTIC $\gamma$-ray telescope has observed Mrk 421 on 66 clear nights from Dec. 07, 2005 to Apr. 30, 2006, totalling $\sim$ 202 hours of on-source observations. Here, we report the detection of...

Factorial moment studies of Cherenkov images (2005)

Razdan, A., Koul, D. K., Koul, M. K., Charagi, S. K.

In this paper we study factorial moments of simulated Cherenkov images of TACTIC type gamma ray telescope for cosmic gamma rays and proton segregation. A comprative and supplemnetary studies between...

Energy resolution of the TACTIC imaging element (2001)

Sathyabama, N, Dhar, V. K, Koul, M. K, Bhat, C. L

We explore here the possibility of using artificial neural network (ANN) for characterization of atmospheric Cerenkov events (progenitor type and energy) detected by the imaging gamma-ray telescope...
