Gamma-ray research is a specialized area of high-energy astrophysics and nuclear physics focused on the detection, characterization, and modeling of electromagnetic radiation with photon energies above approximately 100 keV. This field investigates physical processes such as nuclear transitions, particle acceleration, matter–antimatter annihilation, and non-thermal emission mechanisms in extreme environments, including supernova remnants, pulsars, active galactic nuclei, and gamma-ray bursts. Research activities encompass the development of space- and ground-based gamma-ray observatories, radiation detectors, and analysis techniques to study spectra, temporal variability, and spatial distribution, thereby constraining fundamental physics, cosmic-ray propagation, and high-energy processes in the universe.
Researchers from Skoltech, MEPhI, and the Dukhov All-Russian Research Institute of Automation have proposed a new method to create compact gamma-ray sources that are simultaneously brighter, sharper, and capable of emitting ...
