Dam Removal to Help Restore Spawning Grounds

PODCASTS: Expanding With the Cosmos

Using the Atacama Cosmology Telescope (ATC), a 6.5-meter microwave collector in Chile, cosmologists are piecing together the early history of the known universe. In an exclusive American Scientist interview, Arthur Kosowsky—a member of the ATC team and a professor in the Department of Physics and Astronomy at the University of Pittsburgh—discusses how he is using ATC to reach back in time billions of years to search for gravitational waves that could verify inflation and reveal unprecedented details about how the cosmos was born.
