Numerical Studies of Electron Scattering in Astrophysics.
Abstract
This dissertation consists of three articles that describe the application of numerical methods to astrophysical situations in which a detailed treatment of the scattering of radiation by electrons is required. The common thread that connects these articles is a Monte Carlo computer code that simulates the scattering of photons on relativistic electrons. The first article deals with electronpositron pair production in the spherical accretion flow onto a massive black hole. The second article uses a Monte Carlo code to check analytical expressions which describe the transfer of radiation through the atmosphere above the surface of a neutron star. The final article again treats spherical accretion onto a massive black hole, this time incorporating a detailed treatment of the scattering of photons between relativistically curved photon orbits.
