Work in cosmology, in close collaboration with the theoretical
group, includes analyses of relatively nearby structures from
published data and deep surveys of galaxies using the Hubble
Space Telescope and ground-based telescopes.
The group is on the cutting edge of measurements of the 2.73 K cosmic
background radiation (CMB). The CMB is the after-glow of the hot early
stages of expansion of our universe; in its temperature and angular
distribution are encoded the histories of ionization and structure
formation and of the time-evolution of the rate of expansion of the
universe. Theses generally involve building a sensitive and stable
receiver out of commercial and home-brew parts, and making and analyzing
observations from ground- or balloon-based platforms.
The group is
heavily involved in the WMAP satellite, a partnership between Princeton and
NASA Goddard Space Flight Center. Princeton is the lead partner for the
ACT experiment, and
heavily involved with the QUIET, SPIDER, BiCEP, Planck, and PCAM
experiments to measure the
temperature and polarization anisotropies in the CMB.
