X-ray Intraday Variability of the TeV Blazar Mrk 421 with {\it Chandra}
V. Aggrawal, Ashwani Pandey, Alok C. Gupta +4
We present an extensive study of 72 archival Chandra light curves of the high-frequency-peaked type blazar Mrk 421, the first strong extragalactic object to be detected at TeV ener…
Study of short term enhanced TeV - ray emission from Mrk 421 observed with TACTIC on December 28, 2014
K K Singh, K K Yadav, K Chanchalani +19
In this work, we report on the detection of enhanced TeV gamma- ray emission from the high synchrotron-peaked blazar Mrk 421 with the TACTIC telescope on the night of December 28,…
Multiwavelength study of VHE emission from Markarian 501 using TACTIC observations during April-May, 2012
P Chandra, K K Singh, R C Rannot +23
We have observed Markarian 501 in Very High Energy (VHE) gamma-ray wavelength band for 70.6 hours from 15 April to 30 May, 2012 using TACTIC telescope. Detailed analysis of 6…
A time dependent approach to model X-ray and --ray light curves of Mrk 421 observed during the flare in February 2010
K K Singh, S Sahayanathan, A Sinha +18
Strong X-ray and --ray flares have been detected in February 2010 from the high synchrotron peaked blazar Mrk 421 (z=0.031). With the motivation of understanding the physics inv…
Search for TeV --ray emission from blazar 1ES1218+304 with TACTIC telescope during March-April 2013
K. K. Singh, K. K. Yadav, A. K. Tickoo +22
In this paper, we present results of TeV --ray observations of the high synchrotron peaked BL Lac object 1ES 1218+304 (z=0.182) with the (TeV Atmospheric Cherenkov Tele…
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…
