Astrophysics, Cosmology and Gravitation

Vuk Mandic is involved in searches for gravitational waves with LIGO. He co-chairs the LIGO group searching for the stochastic background of gravitational waves, which could be cosmological or astrophysical in origin. He is also involved in the studies of different noise sources that limit the performance of gravitational-wave detectors, and is leading a collaboration studying the possibility of building such a detector underground.

Physics of The Cosmos
Welcome to the Cosmology Group at the University of Minnesota!
We are a diverse but cohesive group of Physics and Astronomy faculty,
post-docs and graduate students engaged in research work in Cosmology,
Gravitation and related fields. Our research interests span a wide
range of topics in the experimental, theoretical and observational
Cosmology.
On the experimental side we are involved in all aspects of the
Cryogenic Dark Matter Search (CDMS) experiment, in the building of
balloon-borne instruments to detect minute signals from the Big Bang
as imprinted on the Cosmic Microwave Background, and in the Laser
Interferometer Gravitational-wave Observatory (LIGO), a network of
multi-kilometer interferometers designed to search for gravitational
waves. On the theoretical side we investigate the earliest moments of
the Universe, the inflationary epoch whose outcome sets the stage for
the later evolution of galaxies and clusters. We map the mass distribution
in these structures in order to reveal the properties of dark matter.
We also study the origin and evolution of the chemical elements from
their production during the Big Bang Nucleosynthesis and in the interiors
of stars, to their dispersal by supernova and mixing into the interstellar
medium. We carry out observational programs to test theoretical predictions
of the chemical evolution models and to uncover new properties of stars
and galaxies.
Our weekly Monday lunchtime seminars cover a variety of cosmology and
related topics and are generally accompanied by lively discussions. With
the generous help from the Fine Theoretical Physics Institute we organize
yearly workshops that attract international experts.
