摘要：

We have observed the blazar Markarian 421 with the TACTIC gamma-ray telescope at Mt. Abu, India, from 22 November 2009 to 16 May 2010 for 265 h. Detailed analysis of the data so recorded revealed the presence of a TeV gamma-ray signal with a statistical significance of 12.12 sigma at E-gamma >= 1 TeV. We have estimated the time-averaged differential energy spectrum of the source in the energy range 1.0-16.44 TeV. The spectrum fits well with the power-law function of the form (dF/dE = f(0)E(-Gamma)) with f(0) = (1.39 +/- 0.239) x 10(-11) cm(-2) s(-1) TeV-1 and Gamma = 2.31 +/- 0.14.
