On the modulation of low frequency Quasi-Periodic Oscillations in black-hole transients
Devraj D. Pawar, Sara Motta, K. Shanthi +2
We studied the properties of the low-frequency quasi-periodic oscillations detected in a sample of six black hole candidates (XTE J1550-564, H 1743-322, XTE J1859+226, 4U 1630-47,G…
Discovery of twin kHz quasi periodic oscillations in the low mass X-ray binary XTE J1701-407
Devraj D. Pawar, Maithili Kalamkar, Diego Altamirano +5
We report the discovery of kHz quasi periodic oscillations (QPOs) in three Rossi X-ray Timing Explorer observations of the low mass X-ray binary (LMXB) XTE J1701-407. In one of the…
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…
On the incidence of KHz quasi-periodic oscillations in the neutron star system 4U 1636-53
R. Misra, K. Shanthi
Nearly 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 s…
