Experimental and Observational
The University of Chicago is a major center for interdisciplinary research in observational cosmology. Members of the Department of Physics work in close collaboration with members of the Department of Astronomy and Astrophysics. Research in observational cosmology is organized under the Enrico Fermi Institute. Studies of the cosmic microwave background radiation spectrum and anisotropy with ground and space-based detectors. Search for polarization in the cosmic background radiation. Measurements of the Sunyaev-Zelodovich effect for clusters of galaxies. Measurements of intergalactic radiation fields.
Theoretical and Computational
The University of Chicago is a leader in interdisciplinary research in theoretical cosmology, including connections to particle physics, general relativity, and computational physics. Collaboration with the Department of Astronomy and Astrophysics is organized under the Enrico Fermi Institute. The Kavli Institute for Cosmological Physics organizes research, symposia, a visitors program, and education/outreach activities at the interface of phyiscs and astrophysics. We also have close ties to the Fermilab Theoretical Astrophysics Group, which focuses on both early- and late-universe cosmology. Current research topics include Cosmology and elementary particle physics. Big-Bang nucleosynthesis. Tests of the Big Bang model. Baryogenesis and cosmological phase transitions. Topological defects. Inflationary cosmology. Cosmic microwave background radiation. Formation of structure in the universe. The nature of dark energy and connections to string theory and quantum gravity. Aspects of string cosmology. Related work is also performed by faculty in the department of Astronomy and Astrophysics.
