Abstract

A new, very fast method for 3D radiative transfer on fully threaded grids with arbitrarily high angular resolution is presented. The method uses completely cell-based discretization, and is ideally suited for problems with diffuse background radiation, often encountered in cosmological and star formation models. We find that for accurate statistical study of intergalactic Ly α absorption lines, one needs of the order of a few hundred angular discretization elements even for models without radiative feedback from star-forming galaxies.
