Faculty Research

• Matthew Malkan studies the nature of active galactic nuclei and quasars, and has searched for high redshift galaxies associated with quasar absorption line system.
• Ian McLean studies the first generation of galaxies in the Universe by observing their emission redshifted into the infrared.
• Michael Rich is part of a team of astronomers who will measure the age of the Universe from the ages of the oldest white dwarfs in the globular cluster M4. As a byproduct, the Hubble Space Telescope imagery will produce an image as deep as the Hubble Deep Field.
• Edward Wright studies cosmology using infrared astronomy and the cosmic microwave background (CMB). He is the Principal Investigator on the Wide-field Infrared Survey Explorer (WISE) to be launched in 2009, and he has been involved with the Spitzer Space Telescope since 1976. Wright studies the CMB, which gives evidence about the state of the Universe in the first picosecond after the Big Bang, using data from the COsmic Background Explorer (COBE, launched in 1989 - Nobel Prize in Physics 2006) and the Wilkinson Microwave Anisotropy Probe (WMAP, launched in 2001).

Graduate Student Research

• Xi Chen works with Prof. Ned Wright searching for extragalactic point sources in the WMAP data set.
• Louis Levenson works with Professor Ned Wright investigating the Cosmic InfraRed Background using data from COBE/DIRBE, 2MASS, and Spitzer.
