A compact cryogenic configurable slit unit for a multi-object infrared spectrograph:Design and Development of a prototype at TIFR
P. P. Madhwani, A. P. K. Kutty, B. Mookerjea +5
We present a cryogenic configurable slit unit (CSU) for a multi object infrared spectrograph with an effective field of view of 9.1 arcmin x 9.1 arcmin that was completely conceive…
Thermonuclear X-ray bursts in rapid succession in 4U 1636-536 with AstroSat-LAXPC
Aru Beri, Biswajit Paul, J S Yadav +12
We present results from an observation of the Low Mass X-ray Binary 4U 1636-536 obtained with the LAXPC instrument aboard AstroSat. The observations of 4U 1636-536 made during the…
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…
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…
AstroSat/LAXPC observation of Cygnus X-1 in the hard state
Ranjeev Misra, J S Yadav, Jai Verdhan Chauhan +10
We report the first analysis of data from AstroSat/LAXPC observations of Cygnus X-1 in January 2016. LAXPC spectra reveals that the source was in the canonical hard state, represen…
AstroSat/LAXPC reveals the high energy variability of GRS 1915+105 in the chi class
J S Yadav, Ranjeev Misra, Jai Verdhan Chauhan +10
We present the first quick look analysis of data from nine {\it AstroSat}'s LAXPC observations of GRS 1915+105 during March 2016 when the source had the characteristics of being in…
