Cosmology Theory
Working closely with the experimental group, we use
astrophysical, particle physics and
superstring theory combined with observations to study
gravitation
and the origin and evolution of our universe.
The study of the nature of large-scale structure was pioneered in
this group two decades ago, and we continue to make leading
contributions to theories of the origin of this structure.
Crucial elements in the work include the measurements by the
experimental group of the 2.73 K thermal background radiation,
deep observations of galaxies, and the Sloan Digital Sky Survey
that operates out of the neighbouring Department of Astrophysical
Sciences.
One of the principle areas of research is the theoretical
analysis of the cosmic microwave background, large-scale
structure, and the expansion of the universe to test and constrain
cosmological models and measure cosmological parameters.
The origin of the physical universe and the cosmological model
that describes its evolution must ultimately be
explained by fundamental physics. Our group also studies the
relationship between particle/superstring physics
and theories of
the very early universe, dark matter, the
cosmological constant and quintessence.
These studies
have profound implications for both fundamental physics and
cosmology.
