"THE NINTH MARCEL GROSSMANN MEETING On Recent Developments in Theoretical and Experimental General Relativity, Gravitation and R
Physics
Scientific paper
The recent observations of black hole binary systems show more and more clearly that the observed spectra of these systems result from the Comptonization of the high energy electrons close to the black hole on the ambient soft photons. So, in order to model these observed spectra, we have to treat as precisely as possible the Comptonization process, taking into account the real motion of the electrons, which is, in fact, a composition of their free-falling motion onto the black hole and of their brownian motion due to the electron temperature. Whereas the thermal Comptonization has been already explored in details, the effects of the electrons free-falling motion on the resulting Comptonized spectrum is not yet clearly understood. Also, the general relativistic effects close to the black hole were not yet plainly taken into account.
We will then present strong theoretical and observational arguments of the converging inflow effect in accreting black hole binary systems. Our arguments rely on spectral and timing analysis of X-ray radiation from Galactic and Extragalactic black sources supported by analytical and Monte-Carlo calculations of X-ray spectral formation in the converging inflow. The full relativistic treatment has been implemented to reproduce these spectra. We will discuss the issue of pair production, annihilation and high energy line appearances in the converging inflow related with the specific properties of the Schwartzchild space. We will demonstrate that the spectral state transition is regulated by the soft photon flux. We will describe also the work we are making now with our Monte-Carlo tool in order to study the temporal properties of black hole binary systems, in particular to predict the time lags induced by the Comptonization process.
