Abstract
The possibility that the magnetic field is strongly correlated with the large-scale structure of the universe has been considered recently in the literature. In this scenario, the intergalactic magnetic field has a strong (in units of microgauss) regular component spanning tens of megaparsecs but localized in sheets and filaments, while the vast voids in between are almost free of magnetic field. If true, this could have important consequences on the propagation of ultra-high-energy cosmic rays and severely affect our capacity for doing astronomy with charged particles. A quantitative discussion of these effects is given in the present work.Keywords
