Simulating the Glast satellite with Gismo

One of the most interesting yet least explored areas of astrophysics is the gamma ray portion of the electromagnetic spectrum. One of gamma ray astronomy's most significant efforts has been the Compton Gamma Ray Observatory launched in 1991. Scientists from 21 institutions worldwide are now refining the newest gamma ray instrument, the Gamma Ray Large Area Space Telescope (Glast), which will continue CGRO's work. Our group has been involved primarily with software issues, particularly with an object-oriented Monte Carlo package called Gismo, which has modeled all aspects of the satellite's design and performance.
