The production and acceleration mechanisms of ultrahigh-energy cosmic rays (UHECRs) of
energy> 10 20 eV, clearly beyond the GZK cutoff limit, remain unclear, which points to the …

We study the implications of ultrahigh-energy cosmic-ray (UHECR) data from the Pierre
Auger Observatory for potential accelerator candidates and cosmogenic neutrino fluxes for …

We present the first comprehensive discussion of constraints on the cosmic neutrino
background (CνB) overdensity, including theoretical, experimental and cosmological limits …

The origin of extragalactic magnetic fields is still poorly understood. Based on a dedicated
suite of cosmological magneto-hydrodynamical simulations with the ENZO code we have …

In cosmic ray physics extensive progress has been made in recent years, both concerning
theory and observation. The vast details in direct, indirect and secondary detections on the …

In this chapter, we review some features of particle acceleration in astrophysical jets. We
begin by describing four observational results relating to the topic, with particular emphasis …

Dark energy and dark matter constitute 95% of the observable Universe. Yet the physical
nature of these two phenomena remains a mystery. Einstein suggested a long-forgotten …

We propose a new probe of cosmic relic neutrinos (CνB) using their resonant scattering
against cosmogenic neutrinos. Depending on the lightest neutrino mass and the energy …

Lorentz invariance violation (LIV) is often described by dispersion relations of the form E2 i=
m2 i+ p2 i+ δi, nE2+n with delta different based on particle type i, with energy E, momentum …
