In this work, we present results from VHE gamma-ray observations of two blazars namely Mrk 421 (z=0.031) and B20806+35 (z=0.083) with TACTIC telescope performed during 2015-16 campaign. We complement the results of TACTIC with near simultaneous data from Fermi-LAT (Large Area Telescope) observations of the above sources to understand the high energy gamma-ray emission in the energy range 100MeV-300GeV. We also include contemporary archival data from X-ray, optical and radio observations for multi-wavelength study of the above source. |
