Title: NEUTRINOS IN ASTROPHYSICS: GHOSTLY MESSENGERS OF THE HEAVENS

A. Baha Balantekin
Eugene P. Wigner Professor of Physics, University of Wisconsin-Madison

More than half a century after their existence was first postulated, we finally seem to be getting closer to understanding the elusive physics of neutrinos. Their seemingly very small masses and feeble interactions with ordinary matter make neutrinos rather special. For a long time very little experimental information was available about neutrino properties, even though even a small neutrino mass has intriguing cosmological and astrophysical implications. In this talk, after a brief history of the neutrino physics, recent experimental and theoretical developments in solar, atmospheric, and reactor neutrino physics will be reviewed. Implications of these experiments for neutrino physics and astrophysics will be discussed. The role of neutrinos in the dynamics of core-collapse supernovae and the origin of chemical elements will be elucidated.
