A Complete Treatment of
CMB Anisotropies in a FRW Universe
W.Hu, U. Seljak, M.White, M. Zaldarriaga
Abstract
We generalize the total angular momentum method for computing Cosmic Microwave
Background anisotropies to Friedman-Robertson-Walker (FRW) spaces with
arbitrary geometries.
The temperature and polarization anisotropies generated by scalar,
vector and tensor perturbations of the fluid, seed, or scalar field
type, in a universe with constant comoving curvature are brought
into a unified treatment. The resulting formalism generalizes
and simplifies the
calculation of anisotropies and, in its integral form,
allows for a fast calculation of model predictions in
linear theory for any FRW metric. With this work, the perturbation
theory of CMB temperature and polarization anisotropy formation
through gravitational instability in an FRW universe
may be considered complete.
