Gamma-ray Astrophysics with AGILE
AIP Conference Proceedings, 2007AGILE will explore the gamma‐ray Universe with a very innovative instrument combining for the first time a gamma‐ray imager and a hard X‐ray imager. AGILE will be operational in spring 2007 and it will provide crucial data for the study of Active Galactic Nuclei, Gamma‐Ray Bursts, unidentified gamma‐ray sources.

The significance of γ-ray astrophysics lies in its ability to reveal the explosive, high energy, and nuclear phenomena of the universe. Thus, being the indicators of change and evolution, γ-rays provide special insight into the “how” and “why” of the physical processes which govern our universe. Although these features had long been recognized, the low

Abstract Because of the very nature of the production processes. γ-ray astrophysics provides an excellent new opportunity to gain insight into the nature of the Universe. Gamma-ray astronomy permits a very direct study of the largest transfers of energy occurring in astrophysical processes, including rapid expansion processes explosions, high-energy ...

Astrophysics and Space Science, 1994
A general review of cosmic energetic gamma particles is given. A discussion on the subject starting with the discovery of the PeV gamma rays by Sammorski and Stamm, passing to the super-nova SN1987A explosion when several groups waited for high energy gamma particles but none has come so far up to the measurements of TeV gamma incoming from the Crab ...

Space Science Reviews, 1977
γ-ray astronomy is the study of the most energetic photons originating in our Galaxy and beyond, and therefore, provides the most direct means of studying the largest transfers of energy occurring in astrophysical processes. The first certain detection of celestialγ-rays came from a satellite experiment flown on OSO-III (Kraushaaret al., 1972); more ...

Gamma ray production processes are reviewed, including Compton scattering, synchrotron radiation, bremsstrahlung interactions, meson decay, nucleon-antinucleon annihilations, and pion production. Gamma ray absorption mechanisms through interactions with radiation and with matter are discussed, along with redshifts and gamma ray fluxes.

AIP Conference Proceedings, 2000
The Compton Observatory instruments have measured γ-ray lines from several individual sources and from the diffuse interstellar medium. At this late phase of CGRO’s mission, we review the astrophysical achievements by these observations of solar flare spectra, supernova lines from Co and 44Ti isotopes, 511 keV annihilation radiation from Galactic plane

Neutrino and Gamma-Ray Astrophysics
1993Neutrinos and gamma rays are complementary probes of high-energy reactions in astrophysics. The complementarity is due to the respective natures of their interactions: weak vs. electromagnetic. Solar neutrinos probe the nucleosynthesis reactions at the solar core, and possible elementary interactions like neutrino oscillations.

OUTLOOKS ON GAMMA RAY ASTROPHYSICS
2006Gamma Ray Astrophysics, extending from MeV to PeV, covers a wide range of phenomena in the domain of both particle physics and astrophysics, providing one of the most active field of modern astroparticle physics. Moreover, the study of gamma rays from the universe can unveil some profound implications for the foundation of physics itself (from Quantum ...
