Berkeley's world class cosmology group has a venerable history
as a pioneer in large-scale structure,
cosmic microwave background anisotropies, dark matter detection and theory.
The discovery of the microwave anisotropies by COBE in the early 90's
gave us a snapshot of the early universe, revolutionizing our understanding
and paving the way for cosmology as a precision science. On its heels
was the formation of the Center for Particle Astrophysics (CfPA),
a National Science Foundation Science and Technology Center.
Several directions of cutting edge research were funded by the CfPA, including
further experiments to increase our knowledge of the CMB (MAX, MAXIMA,
Boomerang), dark matter searches (CDMS), MACHO searches, and the
supernova cosmology project, significantly shaping our knowledge
in the field today. The supernova cosmology project led to the discovery of
the acceleration of the universe, yet another revolution.
With the end of the CfPA's term,
affiliates of several associated research groups have joined
together informally with previously unaffiliated teams as the Berkeley
The BCG links cosmology research efforts in the Bay Area
based at the UC Berkeley departments of physics and astronomy,
Lawrence Berkeley National Lab and SLAC. The group hosts seminars,
journal clubs and foments camaraderie among post-docs, research
scientists, graduate students and professors. Represented research
activities span the observational and theoretical spectra.
The extensions of the above experiments proceed apace combined with
new ones, such as ACBAR, APEX, CBI, DASI, DEEP2, SNAP, Polarbear and SPT.
Joined with a growing and intensive theory and simulation effort,
the Berkeley Cosmology Group is moving quickly forward in this
golden age of cosmology.
