Axions and other very light axion-like particles appear in many extensions of the Standard
Model, and are leading candidates to compose part or all of the missing matter of the …

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 …

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 …

Most embeddings of the Standard Model into a more unified theory, in particular those
based on supergravity or superstrings, predict the existence of a hidden sector of particles …

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 …

Magnetic reconnection is thought to be the driver for many explosive phenomena in the
universe. The energy release and particle acceleration during reconnection have been …

Context. The background radiation in the optical and the infrared cause energy loss in the
propagation of high energy particles through space. In particular, TeV observations with …

The diffuse extragalactic background light (EBL) is formed by ultraviolet (UV), optical, and
infrared (IR) photons mainly produced by star formation processes over the history of the …
