AstroSat timing and spectral analysis of the accretion-powered millisecond X-ray pulsar IGR J17591--2342
Akshay Singh, Andrea Sanna, Sudip Bhattacharyya +5
IGR J17591--2342, a transient accretion-powered millisecond X-ray pulsar, was discovered during its 2018 outburst. Here, we present a timing and spectral analysis of the source usi…
Discovery of evolving low-frequency QPOs in hard X-rays ( keV) observed in black hole Swift J1727.8-1613 with
Anuj Nandi, Santabrata Das, Seshadri Majumder +3
We report the first detection of evolving Low-Frequency Quasi-periodic Oscillation (LFQPO) frequencies in hard X-rays upto keV with during `unusual' outburst…
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…
Changes in the near-surface shear layer of the Sun
H. M. Antia, Sarbani Basu
We use helioseismic data obtained over two solar cycles to determine whether there are changes in the near-surface shear layer (NSSL). We examine this by determining the radial gra…
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…
