Unveiling the broadband spectral and temporal properties of PKS\,0903-57 during its brightest flare
Zahir Shah, V. Jithesh, S. Sahayanathan +1
We carried a detailed spectral and temporal study of blazar, \mbox{PKS\,0903-57} using the \emph{Fermi}-LAT and \emph{Swift}-XRT/UVOT observations, during its brightest flaring per…
Log-normal flux distribution of bright Fermi blazars
Zahir Shah, N. Mankuzhiyil, A. Sinha +3
We present the results of the -ray flux distribution study on the brightest blazars which are observed by the \emph{Fermi}-LAT. We selected 50 brightest blazars based on the max…
Modeling the response of a standard accretion disc to stochastic viscous fluctuations
Naveel Ahmad, Ranjeev Misra, Naseer Iqbal +2
The observed variability of X-ray binaries over a wide range of time-scales can be understood in the framework of a stochastic propagation model, where viscous fluctuations at diff…
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…
The Effect of X-ray Irradiation on the Time Dependent Behaviour of Accretion Disks with Stochastic Perturbations
Bari Maqbool, Ranjeev Misra, Naseer Iqbal +1
The UV emission from X-ray binaries, is more likely to be produced by reprocessing of X-rays by the outer regions of an accretion disk. The structure of the outer disk may be alter…
