Frequency-dependent core shifts and parameter estimation for the blazar 3C 454.3

Mohan, P. et. al.; Agarwal, A.; Gupta, A. C. (2015)

We study the core shift effect in the parsec-scale jet of the blazar 3C 454.3 using the 4.8– 36.8 GHz radio light curves obtained from three decades of continuous monitoring. From a piecewise Gaussian fit to each flare, ...
Optical and radio variability of BL Lacertae

Gaur, H. et al.; Gupta, A. C.; Agarwal, A. (EDP Sciences, 2015)

Context. We extensively observed the prototype blazar, BL Lacertae, in optical and radio bands during an active phase in the period 2010–2013 when the source showed several prominent outbursts. We searched for possible ...
Rapid variability of blazar 3c 279 during flaring states in 2013−2014 with joint fermi-lat, nustar, swift, and ground-based multi-wavelength observations

Hayashida, M. et. al.; Agarwal, A.; Gupta, A. C. (2015)

We report the results of a multiband observing campaign on the famous blazar 3C 279 conducted during a phase of increased activity from 2013 December to 2014 April, including first observations of it with NuSTAR. The γ-ray ...
