- Professor in Astronomy & Astrophysics Director, Center for Particle Astrophysics, Fermi National Accelerator Laboratory
Hogan was a member of the High-z Supernova Search Team that in 1998 co-discovered dark energy, the mysterious force that works against gravity to accelerate the expansion of the universe. He is currently a member of two international collaborations: the Large Synoptic Survey Telescope (LSST), and the Laser Interferometer Space Antenna (LISA). The LSST is a proposed 8.4-meter telescope that will image faint astronomical objects thousands of times across the entire sky, including exploding stars and potentially hazardous near-Earth asteroids. Expected to launch in the next decade, the satellite-based LISA mission will explore and measure the early universe using gravitational waves. Hogan is designing laboratory experiments using interferometers that will probe the smallest interval of time. He also pursues theoretical studies in astrophysics.
