The Hard X-ray emission of the blazar PKS 2155--304
Haritma Gaur, Liang Chen, R. Misra +4
The synchrotron peak of the X-ray bright High Energy Peaked Blazar (HBL) PKS 2155304 occurs in the UV-EUV region and hence its X-ray emission (0.6--10 keV) lies mostly in the fa…
Gamma-ray Flux Distribution and Non-linear behavior of Four LAT Bright AGNs
Pankaj Kushwaha, Atreyee Sinha, Ranjeev Misra +2
We present a statistical characterization of the -ray emission from the four \emph{Fermi}-LAT sources: FR I radio galaxy NGC 1275, BL Lac Mrk 421, FSRQs B2 1520+31 and PKS 1510-…
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…
Clues on High Energy Emission Mechanism from Blazar 3C 454.3 during 2015 August Flare
Zahir Shah, S. Sahayanathan, Nijil Mankuzhiyil +3
We perform a detailed spectral study of a recent flaring activity from the Flat Spectrum Radio Quasar (FSRQ), 3C\,454.3, observed simultaneously in optical, UV, X-ray and -ray e…
