Gamma ray bursts (GRB) are an especially exciting outflow phenomena that are capable of outputting as much energy as our sun will. Christopher C. . Lindner. 1. Abstract. Relativistic Jets are streams of plasma moving throughout the universe at speeds up to 99% the speed of light. They produce high-energy X-ray, radio, and visible radiation that are observable from great distances across the universe. Davide Lazzati (NCSU). Outline. Prehistory. History. Modern Age. Future.
