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 …

We present an updated review of Lorentz invariance tests in effective field theories (EFTs) in
the matter as well as in the gravity sector. After a general discussion of the role of Lorentz …

We have searched for intermediate-scale anisotropy in the arrival directions of ultrahigh-
energy cosmic rays with energies above 57 EeV in the northern sky using data collected …

The origin of astrophysical high-energy neutrinos detected by the IceCube Neutrino
Observatory remains a mystery to be solved. In this paper we search for neutrino source …

We perform Monte Carlo simulations of transrelativistic shear acceleration dedicated to a jet-
cocoon system of active galactic nuclei. A certain fraction of galactic cosmic rays in a halo is …

We use a new method to estimate the injected mass composition of ultrahigh cosmic rays
(UHECRs) at energies higher than 10 EeV. The method is based on comparison of the …

We derive lower bounds on the density of sources of ultra-high energy cosmic rays from the
lack of significant clustering in the arrival directions of the highest energy events detected at …

Les récentes avancées des mesures et de l'interprétation des rayons cosmiques, depuis la
caractéristique spectrale appelé «cheville» jusqu'aux plus hautes énergies, sont brièvement …

Modern observatories of ultra-high energy cosmic rays (UHECR) have collected over 104
events with energies above 10 EeV, whose arrival directions appear to be nearly …
