Modelling the energy dependent X-ray variability of Mrk 335
K. Akhila, Ranjeev Misra, Rathin Sarma +2
We present a technique which predicts the energy dependent fractional r.m.s for linear correlated variations of a pair of spectral parameters and apply it to an XMM-Newton observat…

Evidence for coronal temperature variation in Seyfert 2 ESO 103--035 using NuSTAR observations
Samuzal Barua, V. Jithesh, Ranjeev Misra +4
We report flux-resolved spectroscopic analysis of the active galactic nucleus (AGN) ESO 103--035 using \textit{NuSTAR} observations. Following an earlier work, we fit the spectra u…

NuSTAR observation of Ark 564 reveals the variation of coronal temperature with flux
Samuzal Barua, V. Jithesh, Ranjeev Misra +3
The hard X-ray spectral index of some AGN has been observed to steepen with the source flux. This has been interpreted in a Comptonization scenario, where an increase in the soft f…
