Disc Winds Matter

The thesis explores the application of a Monte Carlo radiative transfer code to study accretion disc winds in white dwarf binary systems and quasars, revealing new insights across a vast range of mass and size. It demonstrates that disc winds can generate both optical emission lines and a recombination continuum in white dwarfs. Additionally, it presents a model for quasar winds that explains observed signatures, supporting a disc-wind unification scenario. The investigation into emission line equivalent width distribution in quasars poses significant challenges to existing unification theories.
