arc Kamionkowski, assistant professor of physics, has won the prestigious Helen B. Warner Prize for 1998, conferred by the American Astronomical Society.

  The prize is awarded, usually annually, for a significant contribution to observational or theoretical astronomy during the preceding five years by an astronomer who has not yet reached his or her 36th birthday. Kamionkowski, who is 32, was named for his work in a broad spectrum of theoretical fields, including cosmology, astrophysics and particle physics. Most recently, he has concentrated on cosmic microwave background radiation and how it may clarify the origins of the universe.

  David Helfand, professor of astronomy, said: “He is one of the leading young cosmologists in the world who we can expect to make many fundamental contributions to our understanding of the universe in the years ahead.”
