UCR High Energy Astrophysics
One major project is the
Tracking and Imaging Gamma Ray Experiment
(TIGRE), an advanced telescope for detecting and imaging celestial
gamma rays from 0.3 MeV to 100 MeV.
TIGRE employs solid-state detector
technology, allowing dramatic improvements in spatial and energy resolutions
over what is available using standard scintillation detectors.
Over a several year mission,
TIGRE would map the medium-energy
gamma-ray sky with unprecendented detail, exploring sources of positron
annihilation, nuclear line, and continuum emission.
The group at UCR is also active in the analysis and interpretation of
data from various satellites, including the
Compton Gamma Ray Observatory.
The the CGRO Guest Investigator Program, we have explored the application
of novel techniques for extracting scientifically interesting information
from CGRO data. Two major results from these investigations, performed
with collaborators at other institutions, have been the discovery of the
"antimatter cloud" and the
gamma-ray halo
which appears to surround the Milky Way galaxy.
