Multi-wavelength temporal and spectral variability of the blazar OJ 287 during and after the December 2015 flare: a major accretion disc contribution
P. Kushwaha, A. C. Gupta, P. J. Wiita +33
We present a multi-wavelength spectral and temporal analysis of the blazar OJ 287 during its recent activity between December 2015 -- May 2016, showing strong variability in the ne…
A peculiar multi-wavelength flare in the Blazar 3C 454.3
Alok C. Gupta, Arun Mangalam, Paul J. Wiita +20
The blazar 3C454.3 exhibited a strong flare seen in gamma-rays, X-rays, and optical/NIR bands during 3--12 December 2009. Emission in the V and J bands rose more gradually than did…
Core shift effect in blazars
A. Agarwal, P. Mohan, Alok C. Gupta +8
We studied the pc-scale core shift effect using radio light curves for three blazars, S5 0716+714, 3C 279 and BL Lacertae, which were monitored at five frequencies () between 4.…
