Radiation processes around accreting black holes
R. Belmont, J. Malzac, A. Marcowith
Accreting sources such as AGN, X-ray binaries or gamma-ray bursts are known to be strong, high energy emitters. The hard emission is though to originate from plasmas of thermal and…
Simulating acceleration and radiation processes in X-ray binaries
R. Belmont, J. Malzac, A. Marcowith
The high energy emission of microquasars is thought to originate from high energy particles. Depending on the spectral state, the distribution of these particles can be thermal wit…
X-ray spectral states of microquasars
Julien Malzac, Renaud Belmont
We discuss the origin of the dramatically different X-ray spectral shapes observed in the Low Hard State (LHS: dominated by thermal comptonisation) and the High Soft State (HSS: do…
The synchrotron boiler and the spectral states of black hole binaries
Julien Malzac, Renaud Belmont
We study the effects of synchrotron self-absorption on the Comptonising electron distribution in the magnetised corona of accreting black holes. We solve the kinetic equations assu…
A model of the TeV flare of Cygnus X-1: electron acceleration and extended pair cascades
A. A. Zdziarski, J. Malzac, W. Bednarek
We consider theoretical models of emission of TeV photons by Cyg X-1 during a flare discovered by the MAGIC detector. We study acceleration of electrons to energies sufficient for…
Simulating radiation and kinetic processes in relativistic plasmas
R. Belmont, J. Malzac, A. Marcowith
Modelling the emission properties of compact high energy sources such as X-ray binaries, AGN or gamma-ray bursts represents a complex problem. Contributions of numerous processes p…
