Current Topics in Gamma-Ray Astrophysics. [PDF]

J Res Natl Inst Stand Technol, 2000
This paper reports on recent progress toward unraveling the origin of gamma-ray bursts. It is concluded that neutron-star binaries are one of the few remaining candidates. A model is proposed based upon general relativistic hydrodynamic studies which indicate a new physical process by which to power a gamma-ray burst.

Gamma-ray astrophysics in the MeV range [PDF]

Experimental Astronomy, 2021
AbstractThe energy range between about 100 keV and 1 GeV is of interest for a vast class of astrophysical topics. In particular, (1) it is the missing ingredient for understanding extreme processes in the multi-messenger era; (2) it allows localizing cosmic-ray interactions with background material and radiation in the Universe, and spotting the ...

Gamma-ray spectroscopy in astrophysics [PDF]

Nature, 1978
Experimental and theoretical aspects of gamma ray spectroscopy in high energy astrophysics are discussed. Line spectra from solar, stellar, planetary, and cosmic gamma rays are examined as well as HEAO investigations, the prospects of a gamma ray observatory, and follow-on X-ray experiments in space.

AGILE and gamma-ray astrophysics

Nuclear Physics B - Proceedings Supplements, 2003
The study of rays is fundamental for our understanding of the universe: rays probe the most energetic phenomena occurring in nature, and several signatures of new physics are associated with the emission of rays. The main science objectives and the status of the new generation high-energy gamma-ray astrophysics experiment AGILE are presented.

Gamma-ray vortices from nonlinear inverse Thomson scattering of circularly polarized light

Scientific Reports, 2017
Inverse Thomson scattering is a well-known radiation process that produces high-energy photons both in nature and in the laboratory. Nonlinear inverse Thomson scattering occurring inside an intense light field is a process which generates higher harmonic
