Abstract

We present general relativistic radiation transfer formulations which
include opacity effects due to absorption, emission and scattering
explicitly. We consider a moment expansion for the transfer formulation
in the presence of scattering. The formulation is applied to
calculations of emissions from accretion and outflows in black-hole
systems. Cases with thin accretion disks and accretion tori are
considered. Effects, such as emission anisotropy, non-stationary flows
and geometrical self-occultation are investigated. Polarisation transfer
in curved space-time is discussed qualitatively.
