Images and Spectra of Time Dependent Two Component Advective Flow in Presence of Outflows
Arka Chatterjee, Sandip K. Chakrabarti, Himadri Ghosh +1
Two Component Advective Flow (TCAF) successfully explains the spectral and tem- poral properties of outbursting or persistent sources. Images of static TCAF with Compton cloud or C…
Temporal Evolution of Photon Energy emitted from Two Component Advective Flows: Origin of Time Lag
Arka Chatterjee, Sandip K. Chakrabarti, Himadri Ghosh
X-Ray time lag of black hole candidates contains important information regarding the emission geometry. Recently, study of time lags from observational data revealed very intriguin…
Images and Spectral Properties of Two Component Advective Flows Around Black Holes: Effects of Photon Bending
Arka Chatterjee, Sandip K. Chakrabarti, Himadri Ghosh
Two component advective flow (TCAF) successfully explains spectral and timing properties of black hole candidates. We study the nature of photon trajectories in the vicinity of a S…
Numerical Simulation of Spectral and Timing Properties of a Two Component Advective Flow around a Black Hole
Sudip K Garain, Himadri Ghosh, Sandip K Chakrabarti
We study the spectral and timing properties of a two component advective flow (TCAF) around a black hole by numerical simulation. Several cases have been simulated by varying the K…
Quasi Periodic Oscillations in a Radiative Transonic Flow: Results of a Coupled Monte Carlo-TVD Simulation
Sudip K. Garain, Himadri Ghosh, Sandip K. Chakrabarti
Low and intermediate frequency quasi-periodic oscillations (QPOs) in black hole candidates are believed to be due to oscillations of the Comptonizing regions in an accretion flow.…
How Plasma Composition affects the relativistic flows and the emergent spectra
Indranil Chattopadhyay, Sudip Garain, Himadri Ghosh
It has been recently shown that transonic electron positron fluid is the least relativistic, compared to the fluid containing finite proportion of baryons. We compute spectra from…
