AstroSat/LAXPC observation of Cygnus X-1 in the hard state
Ranjeev Misra, J S Yadav, Jai Verdhan Chauhan +10
We report the first analysis of data from AstroSat/LAXPC observations of Cygnus X-1 in January 2016. LAXPC spectra reveals that the source was in the canonical hard state, represen…
Correlated X-ray/UV/optical variability and the nature of accretion disc in the bare Seyfert 1 galaxy Fairall~9
Main Pal, Gulab C. Dewangan, S. D. Connolly +1
We study multi-wavelength variability of a bare Seyfert 1 galaxy Fairall~9 using \swift{} monitoring observations consisting of usable pointings spanning nearly two years and…
Determining the torus covering factors for a sample of type 1 AGN in the local Universe
Savithri H. Ezhikode, Poshak Gandhi, Chris Done +4
In the unified scheme of active galactic nuclei, a dusty torus absorbs and then reprocesses a fraction of the intrinsic luminosity which is emitted at longer wavelengths. Thus, sub…
Multi-wavelength Temporal Variability of the Blazar 3C 454.3 during 2014 Activity Phase
Pankaj Kushwaha, Alok C. Gupta, Ranjeev Misra +1
We present a multi-wavelength temporal analysis of the blazar 3C 454.3 during the high -ray active period from May-December, 2014. Except for X-rays, the period is well sampled…
AstroSat/LAXPC reveals the high energy variability of GRS 1915+105 in the chi class
J S Yadav, Ranjeev Misra, Jai Verdhan Chauhan +10
We present the first quick look analysis of data from nine {\it AstroSat}'s LAXPC observations of GRS 1915+105 during March 2016 when the source had the characteristics of being in…
Detecting Dynamical States from Noisy Time Series using Bicoherence
Sandip V. George, G. Ambika, R. Misra
Deriving meaningful information from observational data is often restricted by many limiting factors, the most important of which is the presence of noise. In this work, we present…
