Date: 26 May 1997
The stochastic method based on the influence functional formalism
introduced in an earlier paper to treat particle creation in
near-uniformly accelerated detectors and collapsing masses is applied
here to treat thermal and near-thermal radiance in certain types of
cosmological expansions. It is indicated how the appearance of thermal
radiance in different cosmological
spacetimes and in the two apparently distinct classes of black hole and
cosmological spacetimes can be understood under
a unifying conceptual and methodological framework.
