Optical Variability of the TeV Blazar 1ES 0806+524 on Diverse Timescales
Ashwani Pandey, Alok C. Gupta, Sofia O. Kurtanidze +14
We report the results of our optical (VRI) photometric observations of the TeV blazar 1ES 0806524 on 153 nights during 2011-2019 using seven optical telescopes in Europe and Asi…
Optical Variability of TeV Blazars on long time-scales
Haritma Gaur, Alok C. Gupta, R. Bachev +12
We present the results of photometric observations of three TeV blazars, 3C 66A, S5 0954+658 and BL Lacertae, during the period 2013--2017. Our extensive observations were performe…
The ever-surprising blazar OJ 287: multi-wavelength study and appearance of a new component in X-rays
Pankaj Kushwaha, Alok C. Gupta, Paul J. Wiita +21
We present a multi-wavelength spectral and temporal investigation of OJ 287 emission during its strong optical-to-X-ray activity between July 2016 - July 2017. The daily -ray fl…
Characterizing optical variability of OJ 287 in 2016 - 2017
Alok C. Gupta, Haritma Gaur, Paul J. Wiita +22
We report on a recent multi-band optical photometric and polarimetric observational campaign of the blazar OJ 287 which was carried out during September 2016 -- December 2017. We e…
