Characterisation of Cosmic Ray Induced Noise Events in AstroSat-CZT Imager
Debdutta Paul, A. R. Rao, Ajay Ratheesh +6
The Cadmium Zinc Telluride (CZT) Imager onboard AstroSat, consists of pixelated CZT detectors, which are sensitive to hard X-rays above 20 keV. The individual pixels are triggered…
Evidence for a high energy curvature in the XMM-Newton spectrum of the ULX NGC1313 X-1
G. C. Dewangan, R. E. Griffiths, A. R. Rao
ASCA X-ray spectra of many ULXs were described in terms of optically thick emission from hot (kT ~1-2keV) accretion disks, while recent XMM-Newton and Chandra observations have rev…
XMM observations of the narrow-line QSO PHL 1092: Detection of a high and variable soft component
Surajit Dasgupta, A. R. Rao, G. C. Dewangan
We present results based on an XMM-Newton observation of the high luminosity narrow-line QSO PHL 1092 performed in 2003 January. The 0.3 - 10 keV spectrum is well described by a mo…
Disk-Jet Connection in Cygnus X-3
M. Choudhury, A. R. Rao, S. V. Vadawale +2
We present the results of a detailed correlation study between the soft X-ray, hard X-ray, and radio emission (obtained from RXTE ASM, BATSE, and GBI observations, respectively) of…
OSSE and RXTE Observations of GRS 1915+105: Evidence for Non-thermal Comptonization
Andrzej A. Zdziarski, J. Eric Grove, Juri Poutanen +2
GRS 1915+105 was observed by the CGRO/OSSE 9 times in 1995-2000, and 8 of those observations were simultaneous with those by RXTE. We present an analysis of all of the OSSE data an…
Understanding Galactic Black Hole Candidate GRS 1915+105
Sandip K. Chakrabarti, S. G. Manickam, A. Nandi +1
We interpret observed features of the black hole candidate GRS1915+105 in the light of the advective flow paradigm. The light curve of this black hole is seen to be of four classes…
