Abstract OCT 2 5 EWe have carried out an experimental and theoretical program in high-energy
astrophysics. We participated in the creation of the Milagro Gamma Ray
Observatory. This facility is a revolutionary advance in high-energy
astrophysics that will be capable of observing TeV radiation from sources
over much of the sky. We built a new class of compact, vibration-free solid
state cryocoolers that will enable space-based infrared imaging and gamma-
ray spectroscopy missions. We developed theoretical models that describe
the dynamical processes in neutron stars and explain how variations in
pulsar periods indicate the occurrence of starquakes. We computed the
encounters between red-giant stars and other stars to determine whether
these events could explain the observed depletion of red-giants towards the
center of the galaxy. We studied chaotic stellar orbits in galactic potentials
with the aim of understanding the equilibrium structures of galaxies and
interpreting recent data from the Hubble Space Telescope.Background and Research Objectives:
We developed the Milagro Observatory to allow the first systematic all-sky survey
to be made at gamma ray energies. In addition, Milagro can provide study of time
variability of sources that have previously been only observed on a limited basis. The
scientific goal of this research is the study of astrophysical sources by the detection of very
high-energy gamma radiation (above -500 GeV). We will extend and expand the studies at
lower energies, up to 10 GeV, which have revealed a number of point sources such as
active galactic nuclei and supernova remnants, as well as diffuse emission, and emission
from some gamma ray bursts.* Principal Investigator, e-mail: epstein@lanl.gov
