The dependence of the estimated luminosities of ULX on spectral models
A. Senorita Devi, R. Misra, V. K. Agrawal +1
Data from {\it Chandra} observations of thirty nearby galaxies were analyzed and 365 X-ray point sources were chosen whose spectra were not contaminated by excessive diffuse emissi…
The Unusual Spectrum of the Ultra Luminous X-ray Source, M82 X-1
V. K. Agrawal, R. Misra
The results of a spectral analysis, using {\it XMM-Newton} and {\it Chandra} data of the brightest ultra luminous X-ray source in the nearby galaxy M82, are presented. The spectrum…
Anti-correlated hard X-ray time lag in GRS 1915+105: evidence for a truncated accretion disc
Manojendu Choudhury, A. R. Rao, Surajit Dasgupta +3
Multi-wavelength observations of Galactic black hole candidate sources indicate a close connection between the accretion disk emission and the jet emission. The recent discovery of…
Detection of absorption features in the X-ray spectrum of the narrow-line Quasar PG 1404+226 : Possible evidence for accretion disk winds
Surajit Dasgupta, A. R. Rao, G. C. Dewangan +1
We present the results of an analysis of data from XMM-Newton and CHANDRA observations of the high luminosity narrow-line quasar PG 1404+226. We confirm a strong soft X-ray excess…
X-ray spectral evolution of low-mass X-ray binary GX 349+2
V. K. Agrawal, P. Sreekumar
We present the results of a systematic investigation of spectral evolution in the Z source GX 349+2, using data obtained during 1998 with Proportional-Counter-Array (PCA) on-board…
