Astrophysics Flies High at APS Meeting in D.C.The elements and forces that shape the universe and are explored in research supported by the National Science Foundation (NSF) are highlighted at the American Physical Society meeting at the Renaissance Hotel in Washington, D.C., April 28-May 1, 2001. Science content of items below is embargoed until the time of presentation. Cosmic Microwave Background: Measurements from the
South Pole - The Degree Angular Scale lnterferometer
(DASI), a microwave detector based in Antarctica,
observes the distribution of early matter as represented
in the minute temperature differences in the cosmic
microwave background radiation. John Carlstrom, leader
of the DASI team, reveals the first results of the
team's test of the inflationary theory of the universe. Imaging the Early Universe: Mapping the Cosmic Microwave
Background - Andrew Lange and the BOOMERANG team,
using a microwave telescope borne by a high-altitude
balloon launched from Antarctica, provided the first
high-resolution images of the cosmic microwave background,
the minute temperature variations in the early universe.
The results led to conclusions about the curvature
of the universe. Lange predicts such precision science
will characterize cosmology in the future. Bouchet Award Recognizes Gravity Research -
Long-time NSF grantee Jorge Pullin of Pennsylvania
State University will receive the 2001 Bouchet Award
for his studies of gravitational wave propagation
and quantum theory of gravity and his efforts to increase
diversity in the field of physics as a founding member
of the National Society of Hispanic Physicists. The
award recognizes the contributions of distinguished
minority physicists. Pullin is exploring quantum gravity
through numerical simulations of the gravity of black
holes. For more information contact:
