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…
Effect of equation of state and composition on relativistic flows
I. Chattopadhyay, S. Mandal, H. Ghosh +3
The thermal state of the fluid is governed by the ratio of the thermal and the rest energy. This brings the composition of the fluid into the picture. Although, fluid composed of l…
Effects of Compton Cooling on outflows in a Two Component Accretion Flow around a Black Hole: Results of a Coupled Monte Carlo-TVD Simulation
Sudip K. Garain, Himadri Ghosh. Sandip K. Chakrabarti
The effect of cooling on the outflow rate from an accretion disk around a black hole is investigated using a coupled Monte Carlo Total Variation Diminishing code. A correlation bet…
