A study of a tilted thin inner accretion disk around a spinning black hole
Srimanta Banerjee, Chandrachur Chakraborty, Sudip Bhattacharyya
The inner part of a thin accretion disk around a Kerr black hole can serve as an important tool to study the physics of the strong gravity regime. A tilt in such a disk with respec…
AstroSat and Chandra view of the high soft state of 4U 1630-47 (4U 1630-472): evidence of the disk wind and a rapidly spinning black hole
Mayukh Pahari, Sudip Bhattacharyya, A R Rao +8
We present the X-ray spectral and timing analysis of the transient black hole X-ray binary 4U 1630-47, observed with the AstroSat, Chandra and MAXI space missions during its soft X…
Long term X-ray variability characteristics of the narrow-line Seyfert 1 galaxy RE~J1034+396
K. Chaudhury, V. R. Chitnis, A. R. Rao +8
We present the results of our study of the long term X-ray variability characteristics of the Narrow Line Seyfert 1 galaxy RE J1034+396. We use data obtained from the AstroSat sate…
Effects of thermonuclear X-ray bursts on non-burst emissions in the soft state of 4U 1728--34
Sudip Bhattacharyya, J. S. Yadav, Navin Sridhar +8
It has recently been shown that the persistent emission of a neutron star low-mass X-ray binary (LMXB) evolves during a thermonuclear (type-I) X-ray burst. The reason of this evolu…
Erratum: "Determining neutron star masses and radii using energy-resolved waveforms of X-ray burst oscillations" (ApJ, 776, 19 [2013])
Ka Ho Lo, M. Coleman Miller, Sudip Bhattacharyya +1
This erratum addresses an error in the text of Lo et al. (2013) and more importantly corrects a computational error that was made in all previously published relativistic computati…
Extensive broadband X-ray monitoring during the formation of a giant radio jet base in Cyg X-3 with AstroSat
Mayukh Pahari, J S Yadav, Jai Verdhan Chauhan +9
We present X-ray spectral and timing behavior of Cyg X-3 as observed by AstroSat during the onset of a giant radio flare on 01-02 April 2017. Within a time-scale of few hours, the…
