CMB Anisotropies: A Decadal Survey
W.Hu
Abstract
We review the theoretical implications of the past decade of
CMB anisotropy measurements, which culminated in the recent
detection of the first feature in the power spectrum,
and discuss the tests available to the next decade of experiments.
The current data already suggest that
density perturbations originated in an inflationary epoch,
the universe is spatially flat,
and baryonic dark matter is required. We discuss the underlying
assumptions of these claims and outline the tests required
to ensure they are robust. The most critical test -
the presence of a second feature at the predicted location
- should soon be available. Further
in the future,
secondary anisotropies and polarization should open new windows to
the early and low(er) redshift universe.
