A fraction of active galactic nuclei producing very high-energy (VHE) $\ensuremath{\gamma}$ rays are located in galaxy clusters. The magnetic field present in the intracluster medium would lead to conversions of VHE photons into axionlike particles (

Very-high energy photons emitted by distant cosmic sources are absorbed on the extragalactic background light (EBL) during their propagation. This effect can be characterized in terms of a photon transfer function at Earth. The presence of extragalac

We perform a study of the ultrahigh energy neutrino detection performances of a km3 neutrino telescope sitting at the three proposed sites for ANTARES, NEMO and NESTOR in the Mediterranean sea. We focus on the effect of the under-water surface profil

More than two years of fluorescence detector data collected in coincidence with at least one station of the surface detector array (“hybrid data”) are used to measure the flux and energy spectrum of cosmic rays above about 10**18 eV. The hybrid m

Earth–skimming UHE tau neutrinos have a chance to be detected by the Fluorescence Detector (FD) of Pierre Auger Observatory if their astrophysical flux is large enough. A detailed evaluation of the expected number of events is here performed for a
