X-ray timing analysis of Cyg X-3 using AstroSat/LAXPC: Detection of milli-hertz quasi-periodic oscillations during the flaring hard X-ray state
Mayukh Pahari, H. M. Antia, J. S. Yadav +10
We present here results from the X-ray timing and spectral analysis of the X-ray binary Cyg X-3 using observations from Large Area X-ray Proportional Counter (LAXPC) on-board Astro…
Large Area X-ray Proportional Counter (LAXPC) Instrument on AstroSat and Some Preliminary Results from its performance in the orbit
P. C. Agrawal, J. S. Yadav, H. M. Antia +25
Large Area X-ray Propositional Counter (LAXPC) instrument on AstroSat is aimed at providing high time resolution X-ray observations in 3 to 80 keV energy band with moderate energy…
Sensitivity of Helioseismic Measurements of Normal-mode Coupling to Flows and Sound-speed Perturbations
Shravan M. Hanasoge, Martin Woodard, H. M. Antia +2
In this article, we derive and compute the sensitivity of measurements of coupling between normal modes of oscillation in the Sun to underlying flows. The theory is based on first-…
Large Area X-ray Proportional Counter (LAXPC) Instrument on AstroSat
J. S. Yadav, P. C. Agrawal, H. M. Antia +3
Large Area X-ray Proportional Counter (LAXPC) is one of the major AstroSat payloads. LAXPC instrument will provide high time resolution X-ray observations in 3 to 80 keV energy ban…
AstroSat/LAXPC detection of milli-second phenomena in 4U 1728-34
Jai Verdhan Chauhan, J S Yadav, Ranjeev Misra +10
The low mass X-ray binary 4U 1728-24 was observed with AstroSat/LAXPC on 8th March 2016. Data from a randomly chosen one orbit of over 3 ks was analyzed for detection of rapid inte…
Calibration of the Large Area X-ray Proportional Counter (LAXPC) instrument on-board AstroSat
H. M. Antia, J. S. Yadav, P. C. Agrawal +21
We present the calibration and background model for the Large Area X-ray Proportional Counter (LAXPC) detectors on-board AstroSat. LAXPC instrument has three nominally identical de…
