VHE Gamma-ray Observation of Crab Nebula with HAGAR Telescope Array
B. B. Singh, R. J. Britto, V. R. Chitnis +13
HAGAR is a system of seven Non-imaging Atmospheric Cherenkov Telescopes located at Hanle in the Ladakh region of the Indian Himalayas at an altitude of 4270 meters {\it amsl}. Sinc…
Long-term study of Mkn 421 with the HAGAR Array of Telescopes
Atreyee Sinha, Amit Shukla, Lab Saha +8
Context:The HAGAR Telescope Array at Hanle, Ladakh has been regularly monitoring the nearby blazar Mkn 421 for the past 7yrs. Aims: Blazars show flux variability in all timescales…
Multi-frequency, Multi-Epoch Study of Mrk 501: Hints for a two-component nature of the emission
A. Shukla, V. R. Chitnis, B. B. Singh +8
Since the detection of very high energy (VHE) -rays from Mrk 501, its broad band emission of radiation was mostly and quite effectively modeled using one zone emission scenario.…
Multiwavelength study of TeV Blazar Mrk421 during giant flare
A. Shukla, V. R. Chitnis, P. R. Vishwanath +7
Context: The nearby (z=0.031) TeV blazar Mrk421 was reported to be in a high state of flux activity since November, 2009. Aims: To investigate possible changes in the physical para…
Multiwavelength study of TeV Blazar Mrk421 during giant flare and observations of TeV AGNs with HAGAR
A. Shukla, P. R. Vishwanath, G. C. Anupama +7
The radiation mechanism of very high energy -ray emission from blazars and crucial parameters like magnetic field, and size of the emitting region are not well understood yet. T…
Observations of AGNs using PACT
D. Bose, V. R. Chitnis, P. R. Vishwanath +5
We report our observations on 4 AGNs viz, Mkn421, Mkn501, 1ES1426+428 and ON231 belonging to a sub-class called blazars. The observations were carried out using the Pachmarhi Array…
