The spectral and temporal properties of an Ultra-Luminous X-ray source in NGC 6946 (2008)
Devi, A. Senorita, Misra, R., Shanthi, K., Singh, K. Y.
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 of the high and low...
On the incidence of KHz quasi-periodic oscillations in the neutron star system 4U 1636-53 (2004)
Nearly $1.32 \times 10^6$ sec of non-zero count rate data were obtained from five years of {\rm RXTE} observations of the atoll source 4U 1636-53. The data was divided into 10309 segments of 128 sec...
