AstroSat view of IGR J17091-3624 and GRS 1915+105: decoding the 'pulse' in the 'Heartbeat State'
Tilak Katoch, Blessy E. Baby, Anuj Nandi +3
IGR J17091--3624 is a transient galactic black hole which has a distinct quasi-periodic variability known as `heartbeat', similar to the one observed in GRS 1915+105. In this paper…
AstroSat view of GRS 1915+105 during the Soft State: Detection of HFQPOs and estimation of Mass and Spin
Sreehari H., Anuj Nandi, Santabrata Das +4
We report the results of AstroSat observations of GRS 1915105 obtained using 100 ks guaranteed-time (GT) during the soft state. The Color-Color Diagram (CCD) indicates a variabi…
AstroSat and MAXI view of the Black Hole binary 4U 1630-472 during 2016 and 2018 Outbursts
Blessy E. Baby, V. K. Agrawal, Ramadevi M. C. +4
We present an in-depth spectral and timing analysis of the Black Hole binary 4U 1630-472 during 2016 and 2018 outbursts as observed by \textit{AstroSat} and \textit{MAXI}. The exte…
AstroSat/LAXPC view of GX 17+2: Spectral Evolution along the Z-track
V. K. Agrawal, Anuj Nandi, M. C. Ramadevi
In this paper, we present the first results obtained using 50 ks observations of the bright low-mass X-ray binary (LMXB) GX 17+2 with Large Area X-ray Proportional Counter (…
Additional Calibration of the Ultra-Violet Imaging Telescope on board AstroSat
S. N. Tandon, J. Postma, P. Joseph +20
Results of the initial calibration of the Ultra-Violet Imaging Telescope (UVIT) were reported earlier by Tandon et al. (2017). The results reported earlier were based on the ground…
