Constraining the Coronal Heights and Readjustment Velocities Based on the Detection of a Few Hundred Seconds Delays in the Z Source GX 17+2
K. Sriram, S. Malu, C. S. Choi
Neutron star Z type sources provide a unique platform in order to understand the structure of accretion disk-corona geometry emitting close to the Eddington luminosity. Using RXTE…
Influence of Comptonization region over the ambiance of accretion disc in Active Galactic Nucleus
K. Sriram, D. Nour, C. S. Choi
Understanding the radiative and physical structures of inner region of a few 100 pc of AGNs is important to constrain the causes of their activities. Although the X-ray emission fr…
Spectro-temporal studies of rapid transition of the quasi periodic oscillations in the black hole source H1743-322
K. Sriram, S. Harikrishna, C. S. Choi
An appearance or disappearance of QPOs associated with the variation of X-ray flux can be used to decipher the accretion ejection mechanism of black hole X-ray sources. We searched…
Anti-correlated time lags in the Z source GX 5-1: Possible evidence for a truncated accretion disk
K. Sriram, C. S. Choi, A. R. Rao
We investigate the nature of the inner accretion disk in the neutron star source GX 5-1 by making a detailed study of time lags between X-rays of different energies. Using the cros…
Fast transition of type-B QPO in the black hole transient XTE J1817-330
K. Sriram, A. R. Rao, C. S. Choi
The evolution of different types of quasi-periodic oscillations (QPOs) and the coupled radiative/physical changes in the accretion disk are still poorly understood. In a few black…
