14 de feb. de 2022 · We examine the characteristics of the propagation of cosmic rays inferred from the observations of gamma-ray haloes and their local and global implications for particle transport within the...
1 de jul. de 2021 · Phenomenologically, γ -rays can be found in all high-energy and extreme cosmic events. γ -ray observation can be used to detect and study cosmic events such as supernova explosions, active galactic nuclei, black holes, gamma pulsars, dark matter and etc. In general, γ -rays provide a unique window on the extreme universe in astronomy [2].

Progress in γ-ray astronomy has been very encouraging in recent years. These observations provide the most direct means of studying the largest transfer of energy occurring in astrophysical processes: the dynamic effects of the energetic charged cosmic-ray particles, element synthesis, and particle acceleration.

Ultra-high-energy (UHE, >0.1 PeV) γ-ray astronomy is rapidly evolving into an expanding branch of γ-ray astronomy with the surprising discovery of 12 PeVatrons and the detection of a handful of photons above 1 PeV.
The gamma-ray-emitting NS population exhibits roughly equal numbers of radio-loud and radio-quiet young INSs, plus an astonishing, and unexpected, group of isolated and binary millisecond pulsars (MSPs).
5 de sept. de 2017 · Nature Astronomy - Linearly polarized optical emission from a gamma-ray burst reveals the presence of a large-scale distorted magnetic field in the heart of this powerful cosmic explosion.
30 de dic. de 2021 · Abstract. Very high energy (VHE) \ (\gamma \) -rays constitute one of the main pillars of high energy astrophysics. Gamma-rays are produced under extreme relativistic conditions in the Universe. VHE \ (\gamma \) -rays can be detected indirectly on the ground.
