High Energy Astrophysics

This group has carried out studies from high altitude balloons and from spacecraft. The principal UNH satellite based studies were carried aboard the Solar Maximum Mission and the Gamma Ray Observatory satellites. The UNH detectors measured emissions from the sun and from a number of galactic sources. Galactic gamma rays often are produced by the most dynamic and highest temperature plasmas in the universe. Efforts have concentrated on identifying and mapping sources, on studying the time dependence of emissions, on determining the spectrum and line structure of the sources, and on studies of the cosmic diffuse background radiation. The student designed CATSAT satellite, which is described separately below, is built to study gamma ray bursts.
