Implications of strong intergalactic magnetic fields for ultrahigh-energy cosmic-ray astronomy
Original language description
We study the propagation of ultrahigh-energy cosmic rays in the magnetized cosmic web. We focus on the particular case of highly magnetized voids (B similar to nG), using the upper bounds from the Planck satellite. The cosmic web was obtained from purely magnetohydrodynamical cosmological simulations of structure formation considering different power spectra for the seed magnetic field in order to account for theoretical uncertainties. We investigate the impact of these uncertainties on the propagation of cosmic rays, showing that they can affect the measured spectrum and composition by up to. similar or equal to 80% and. similar or equal to 5%, respectively. In our scenarios, even if magnetic fields in voids are strong, deflections of 50 EeV protons from sources closer than similar to 50 Mpc are less than 15 degrees in approximately 10-50% of the sky, depending on the distribution of sources and magnetic power spectrum.
