1977 through 1979 at or near the Galactic center; and (2) a steady, diffuse interstellar source of 511 keV annihilation line and orthopositronium continuum emission, having a galactic longitudinal distribution consistent with that of the more than 70 MeV gamma rays or the molecular (CO) gas. ...
However, the burst has already shed light on secrets of the Milky Way galaxy, including the nature of its distant dust clouds, through phenomena involving the gamma-ray jet’s X-ray waves. As the X-rays travel toward us and through the dust clouds, the rays are reflected into so-called ...
IN a letter to NATURE of December 4, Prof. J. A. Gray pointed out that a study of radiations of shorter wave-length than 0.02 脜.U. is complicated by the scattered radiations accompanying them, about which little is known. That gamma rays under certain experimental conditions appear to ...

We explore the potential of INTEGRAL to improve our understanding of the low fluence regime for explosive transients, such as GRBs. We probe the nature of the so-called "WEAK" INTEGRAL triggers, when the gamma-ray instruments record intensity spikes that are below the usual STRONG significance...

Gamma-rays from the Large Scale Structure of the Universe Gamma-ray astronomy will play a crucial role in the investigation of nonthermal processes in the large scale structure of the universe. Particularly, galaxy clusters (GC) observations at this photon energy will help us understand the ori....
