Improved background model for the Large Area X-ray Proportional Counter (LAXPC) instrument on-board AstroSat
H. M. Antia, P. C. Agrawal, Tilak Katoch +3
We present an improved background model for the Large Area X-ray Proportional Counter (LAXPC) detectors on-board AstroSat. Because of the large collecting area and high pressure, t…
Studies of Cepheus X-4 during 2018 outburst observed with AstroSat
Kallol Mukerjee, H. M. Antia
We present timing and spectral results of 2018 outburst of Cepheus X-4, observed twice by AstroSat at luminosity of erg s and erg…
Large Area X-ray Proportional Counter (LAXPC) in Orbit Performance : Calibration, background, analysis software
H. M. Antia, P. C. Agrawal, Dhiraj Dedhia +8
The Large Area X-ray Proportional Counter (LAXPC) instrument on-board AstroSat has three nominally identical detectors for timing and spectral studies in the energy range of 3--80…
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 observations of GRO J2058+42 during the 2019 outburst
Kallol Mukerjee, H. M. Antia, Tilak Katoch
We present results from AstroSat observation of the recent outburst of GRO J2058+42, an X-ray pulsar in a Be-binary system. The source was observed on April 10, 2019 by LAXPC and S…
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…
