Abstract
The propagation of the highest energy cosmic rays through the intergalactic magnetic field is considered, including the effect of interactions with the 2.7 K microwave background. Energy loss in the microwave background due to photo-pion production limits the total distance travelled by the cosmic rays and the turbulent intergalactic field determines their total displacement. At energies above 10<sup>20</sup> eV, the average displacements are a few tens of megaparsecs, limiting possible sources to the volume dominated by the supergalactic plane. © 1997 Elsevier Science B.V.
