TeV Gamma-ray Observations of Markarian 421 using TACTIC during 2009-10
P. Chandra, R. C. Rannot, K. K. Yadav +24
We have observed the blazar Markarian 421 with the TACTIC -ray telescope at Mt. Abu, India, from 22 November 2009 to 16 May 2010 for 265 hours. Detailed analysis of the data so…
Simulation studies for optimizing the trigger generation criteria for the TACTIC telescope
M. K. Koul, A. K. Tickoo, V. K. Dhar +7
In this paper, we present the results of Monte Carlo simulations of -ray and cosmic ray proton induced extensive air showers as detected by the TACTIC atmospheric Cherenkov ima…
Very High-energy Gamma-Ray Episodic Activity of Radio Galaxy NGC 1275 in 2022-2023 Measured with MACE
S. Godambe, N. Mankuzhiyil, C. Borwankar +37
The radio galaxy NGC 1275, located at the central region of Perseus cluster, is a well-known very high-energy (VHE) gamma-ray emitter. The Major Atmospheric Cherenkov Experiment Te…
Search for TeV -rays from H1426+428 during 2004-07 with the TACTIC telescope
K. K. Yadav, R. C. Rannot, P. Chandra +15
The BL Lac object H1426+428 () is an established source of TeV -rays and detections of these photons from this object also have important implications for estima…

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…
Artificial Neural Network based gamma-hadron segregation methodology for TACTIC telescope
V. K. Dhar, A. K. Tickoo, M. K. Koul +8
The sensitivity of a Cherenkov imaging telescope is strongly dependent on the rejection of the cosmic-ray background events. The methods which have been used to achieve the segrega…
