Gamma Ray Bursts
Mentors: Dr. James Ling and Dr. Martin Lo (JPL)
BATSE (Burst and Transient Source Experiment) was designed to observe and locate gamma ray bursts. It was aslo used for studying the transient sources, x-ray pulsars and solar flares. BATSE consists of 8 non-collimated detector modules arranged on the Compton Gamma Ray Observatory (CGRO). Each module contains a large area detector (LAD), responsible for the sensitivity and directional response for locating gamma ray bursts. Since the observations are photon count, tomographic imaging technique called the Radon Transform is used to turn these photon counts into images of the sky at the gamma ray energy range between 20KeV to 2MeV. If there are any new gamma ray sources that can be black holes, supernovae or quasars, they will be detectable in the images.
