The Physics of Gamma-Ray Bursts - Kindle edition by Zhang, Bing. Download it once and read it on your Kindle device, PC, phones or tablets. Use features like bookmarks, note taking and highlighting while reading The Physics of Gamma-Ray Bursts.5/5(1). The Physics of Gamma-Ray Bursts 1st Edition including perspectives on the possible developments expected from future observations. It then goes on to place GRBs in the broader astrophysical context of stars, galaxies and the universe, and the possible implications for fundamental physics. Cited by: 9. Astronomical gamma-ray bursts, short lived flashes of high-energy radiation, have eluded even a basic explanation for over twenty years. The Los Alamos Workshop on Gamma-Ray Bursts brought together many international scientists to summarize the current understanding of these enigmatic events, and to describe the directions of current and future by: Gamma-rays coming from space are mostly absorbed by the Earth's gamma-ray astronomy could not develop until it was possible to get our detectors above all or most of the atmosphere, using balloons or spacecraft. The first gamma-ray telescope carried into orbit, on the Explorer XI satellite in , picked up fewer than cosmic gamma-ray photons.
Until recently, gamma-ray bursts could arguably have been called the biggest mystery in high-energy astronomy. Today, however, evidence from recent satellites like Swift and Fermi indicate that the energy behind a gamma-ray burst comes from the collapse of matter into a black hole. However, the type of collapse depends on the type of gamma-ray. Abstract. Some basic observed properties of gamma-ray bursts are reviewed. Although some properties were known 25 years ago, new and more detailed observations have been made by the Compton Observatory in the past three : Gregory J. Fishman. Gamma-ray bursts were first observed in the late s by the U.S. Vela satellites, which were built to detect gamma radiation pulses emitted by nuclear weapons tested in space. On July 2, , at UTC, the Vela 4 and Vela 3 satellites detected a flash of gamma radiation unlike any known nuclear weapons signature. Uncertain what had happened but not considering the matter particularly. This paper shows how much can be done, but to get results like this consistently, we will need new rapid-response facilities for observing gamma-ray bursts.” In addition to the gamma-ray and optical light observations, NASA’s Swift Gamma-ray Burst Mission spacecraft captured X-ray and ultraviolet data.
Cosmic gamma ray bursts (GRBs) have fascinated scientists and the public alike since their discovery in the late s. Their story is told here by some of the scientists who participated in their discovery and, after many decades of false starts, solved the problem of their origin. Get this from a library!
