Long term X-Ray Observations of Seyfert 1 Galaxy Ark 120: On the origin of soft-excess
Prantik Nandi, Arka Chatterjee, Sandip K. Chakrabarti +1
We present the long-term X-ray spectral and temporal analysis of a 'bare-type AGN' Ark 120. We consider the observations from XMM-Newton, Suzaku, Swift, and NuSTAR from 2003 to 201…
Time-domain variability properties of XTE J1650-500 during its 2001 outburst: Evidence of disc-jet connection
Arka Chatterjee, Broja G. Dutta, Prantik Nandi +1
Evolution of variability properties of Galactic transient sources is a diagnostic tool to understand various regimes of the accretion flow and its dynamics close to the central bla…
Evidence of Outflow Induced Soft Lags of Galactic Black Holes
Dusmanta Patra, Arka Chatterjee, Broja G. Dutta +2
The nature of lag variation of Galactic black holes remains enigmatic mostly because of nonlinear and non-local physical mechanisms which contribute to the lag of the photons comin…
Evolution of Accretion Disc Geometry of GRS~1915+105 during its state as revealed by TCAF solution
Broja G Dutta, Partha Sarathi Pal, Sandip K Chakrabarti
The evolution of the C-type low frequency quasi-periodic oscillations (LFQPOs) and associated time lag in transient black hole sources as a function of time can be explained by var…
