GMS: The Compton Legacy: A Quarter

The first gamma-ray telescope carried into orbit, on the Explorer XI satellite inpicked up fewer than cosmic gamma-ray photons. 1981the problem in understanding stellar coronae in general is how to scale up the solar model to account for the enhanced luminosities.

These constitute most of the gamma-ray bursts that our satellites detect, and they are also brighter and easier to pinpoint. AMEGO-X will detect gamma-ray photons both via Compton interactions and pair production processes, bridging the "sensitivity gap" between hard X-rays and high-energy gamma rays. From a Few Bursts to Thousands With the launch of the Compton Gamma-Ray Observatory by NASA in 1991, astronomers began to identify many more bursts and to learn more about them Figure 1.

Within 2 days, the largest telescope in the world the Keck in Hawaii collected enough light to record a spectrum of the burst. The mystery we will discuss in this section was first discovered in the mid-1960s, not via Gamma-ray astronomy in the Compton era research, but as a result of a search for the tell-tale signs of nuclear weapon explosions.

All of the authors of this work are leading and experienced experts and practitioners who have designed, built, tested, calibrated, launched and operated advanced observing equipment for space astronomy. It featured four main telescopes in one spacecraft, covering X-rays and gamma rays, including various specialized sub-instruments and detectors.

Edition Notes Other titles Gamma ray astronomy in the Compton era Contributions Goddard Space Flight Center. Looking into the night sky, one sometimes feels that the visible Universe is a calm, comfortable place. The Einstein SSS measurement showed the X-ray spectrum to be two component with 6 7 temperatures of 7. The four detectors were typically operated in pairs of two. Because of the requirement for a near coincidence between the two interactions, with the correct delay of a few nanoseconds, most modes of background production were strongly suppressed.

In this paper we report a continuous observation through the secondary eclipse of Algol using the EXOSAT Observatory. Networking to Catch More Bursts After initial observations showed that the precise locations and afterglows of gamma-ray bursts could be found, astronomers set up a system to catch and pinpoint bursts on a regular basis. Summary One of the most attractive features of the young discipline of Space Science is Gamma-ray astronomy in the Compton era many of the original pioneers and key players involved are still available to describe their field.

The leading model involves the merger of two compact stellar corpses: two neutron stars, or perhaps a neutron star and a black hole. CGRO was built by TRW now Northrop Grumman Aerospace Systems in Redondo Beach, California. According to general relativity which will be discussed inthe orbits of a binary star system composed of such objects should slowly decay with time, eventually after millions or billions of years causing the two objects Gamma-ray astronomy in the Compton era slam together in a violent but brief explosion.

Astronomy Picture of the Day. Compton's many findings included the discovery of a new class of galaxy powered by supermassive black holes, the surprising detection of gamma rays from thunderstorms on Earth, and the most persuasive evidence to date that gamma-ray bursts GRBs were the most distant and powerful explosions in the cosmos.

Compton was the second of NASA's Great Observatories, a series of ambitious astronomical satellites designed to explore different parts of the electromagnetic spectrum.

This is based on the similarity of the X-ray spectrum and luminosity of this system to that of the RS CVn binaries which also contain K sub-giants with similar rotation periods and the fact that the luminosity of any coronae surrounding the B8 V and AV companion stars should not be enhanced by rapid rotation Pallavicini et al 1980, White et al 1980.
