Nuclear Astrophysics with Gamma-Ray Line Astronomy
EAS Publications Series, 2007Nuclear reactions occur in cosmic environments in the cores of stars and in stellar explosions. Nuclear energy production is a key agent in these objects; the production of new isotopes drives the chemical evolution of gas throughout the universe and of the objects which form from this gas over cosmic times.

Space-Based Gamma-Ray Astrophysics
2018Cosmic gamma-rays of energies above the electron mass are messengers of the most powerful phenomena in our Universe. In this review we focus on gamma-ray astrophysics in the energy range 30 MeV–100 GeV which requires sophisticated instruments on board of satellites operating above the Earth atmosphere.

Gamma-ray astrophysics: parsecs to megaparsecs
Astrophysics and Space Science, 1995A rapidly spinning, slowly accreting magnetic white dwarf (or X-ray pulsar) in hibernation is expected to result in rapid spindown as a result of the stretching and reconnection of magnetic field lines, leading to particle acceleration at the magnetospheric radiusoutside the corotation radius, and the propeller type ejection of magnetized synchrotron ...

Astrophysics: NASA eyes up gamma rays
Physics World, 2000Last month NASA selected the main experiment for its Gamma-Ray Large Area Space Telescope (GLAST), scheduled for launch in 2005. The decision comes at a crucial moment in the history of gamma-ray astronomy. The nine-year-old Compton Gamma Ray Observatory (CGRO) may have to be crash-landed after one of its stabilizing gyroscopes failed, and in any case ...

Galactic gamma-ray astrophysics with VERITAS
Advances in Space Research, 2019Abstract The Galaxy contains a small but quite significant population of highly energetic denizens: supernova remnants with fast shocks, pulsars with powerful winds, intensely-interacting binary systems built from a compact object and a massive star.

Cosmic Rays and Gamma-Ray Astrophysics
2018The history of gamma-ray astronomy, or the non-thermal astrophysics in general, is quite recent. It goes back only to the 20th century, when the physicist Victor Hess discovered what was thought to be a new kind of radiation that would forever change our conception of the Universe.

Gamma-Ray Astrophysics and Galactic Structure
1977Gamma-ray data (together with far-infrared and radio observations) are a powerful tool to study large-scale galactic structure, because of the absence of absorption even for column densities up to ∿ 1026 cm−2 Two satellite experiments have brought us gamma-ray intensities for Eγ > 35 M (Ficlitel et al., 1975, COS B Caravane Collaboration 1976).
