Description
Neutrinos are special among elementary particles in that they
interact extremely weakly, their masses are extremely small, and
they show the phenomenon of flavor oscillations, a macroscopic
quantum interference effect, which allows them to convert from one
type (or flavor) to another. They play a dominant dynamical role in
the early universe and in core-collapse supernovae, may be
responsible for the cosmic matter-antimatter asymmetry, and they
carry crucial information about the highest-energy astrophysical
phenomena - the field of neutrino astronomy has only just begun. We
will review the role of these elusive particles in physics,
astrophysics and cosmology.
