Photon-conserving Comptonization in simulations of accretion discs around black holes
Photon-conserving Comptonization in simulations of accretion discs around black holes
We introduce a new method for treating Comptonization in computational fluid dynamics. By construction, this method conserves the number of photons. Whereas the traditional 'blackbody Comptonization' approach assumes that the radiation is locally a perfect blackbody and therefore uses a single parameter, the radiation temperature, to describe the radiation, the …
