The spectral and temporal properties of an Ultra-Luminous X-ray source in NGC 6946
A. Senorita Devi, R. Misra, K. Shanthi +1
We report variability of the X-ray source, X-7, in NGC 6946, during a 60 ksec Chandra observation when the count rate decreased by a factor of ~1.5 in ~5000 secs. Spectral fitting…
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…
Accretion Disk Spectra of the Brightest Ultra-luminous X-ray Source in M82
Feng Yuan, Ronald E. Taam R. Misra, Xue-Bing Wu +1
Emission spectra of hot accretion disks characteristic of advection dominated accretion flow (ADAF) models are investigated for comparison with the brightest ultra-luminous source,…
The effect of dissipative corona on the structure and stability of cold optically thick accretion disks at high accretion rates
Ranjeev Misra, R. E. Taam
The vertical structure of optically thick accretion disks is investigated in the two-zone approximation. The disk is divided into an underlying disk and a corona, where the latter…
Comparisons of various model fits to the Iron line profile in MCG-6-30-15
R. Misra, F. K. Sutaria
The broad Iron line in MCG-6-30-15 is fitted to the Comptonization model where line broadening occurs due to Compton down-scattering in a highly ionized optically thick cloud. Thes…
Broadening of the Iron emission line in MCG-6-30-15 by Comptonization
R. Misra, A. K. Kembhavi
We show that the Iron K emission line from MCG-6-30-15 could be broadened due to Comptonization by a surrounding highly ionized cloud with radius cms. We calculate t…
