We review the possible mechanisms for the generation of cosmological magnetic fields,
discuss their evolution in an expanding Universe filled with the cosmic plasma and provide a …

One of the most promising ways to probe intergalactic magnetic fields (IGMFs) is through
gamma rays produced in electromagnetic cascades initiated by high-energy gamma rays or …

The extragalactic background light (EBL) is of fundamental importance both for
understanding the entire process of galaxy evolution and for γ-ray astronomy, but the overall …

Magnetic fields in galaxies are produced via the amplification of seed magnetic fields of
unknown nature. The seed fields, which might exist in their initial form in the intergalactic …

Attenuation of high-energy gamma-rays by pair production with ultraviolet, optical and
infrared (IR) extragalactic background light (EBL) photons provides a link between the …

Context. Extended and delayed emission around distant TeV sources induced by the effects
of propagation of γ ray s through the intergalactic medium can be used for the measurement …

The landscape of high-and ultra-high-energy astrophysics has changed in the last decade,
largely due to the inflow of data collected by large-scale cosmic-ray, gamma-ray, and …

Abstract The ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana) Project led by
the Italian National Institute for Astrophysics (INAF) is developing and will deploy at the …

This catalog summarizes 117 high-confidence⩾ 0. 1 GeV gamma-ray pulsar detections
using three years of data acquired by the Large Area Telescope (LAT) on the Fermi satellite …

The Cherenkov Telescope Array (CTA), the new-generation ground-based observatory for γ-
ray astronomy, provides unique capabilities to address significant open questions in …
