Overview: Cosmology

On the observational side of cosmology, Tyson heads the Deep Lens Survey and the future Large Synoptic Survey Telescope (LSST). Other observational faculty (Becker, Boeshaar, Lubin, and Fassnacht) probe dark matter and dark energy through gravitational lensing, high-redshift quasars and the reionization of the Universe, high-redshift clusters of galaxies and the assembly and evolution of large-scale structures, low-mass stars and brown dwarfs, and wide-area optical and radio surveys. Theoretical faculty (Albrecht, Knox, and Kaloper) study the implications of modern ideas of high energy physics for the early Universe (and vice-versa), dark energy, dark matter, predictions of observable effects, and analysis and interpretation of cosmological data with an emphasis on its implications for fundamental physics.
