Research output: Contribution to journalConference articlepeer-review


It is suggested that essentially all of the UHECR we detect originate in our Galaxy. It is shown that even if the density of sources decreases with Galactic radius, assuming it originates from the same material as low energy cosmic rays, then the anisotropy and composition can be better understood. Inward anisotropy, as recently reported by the Auger collaboration can be understood as drift along the current sheet of UHECR originating outside the solar circle, while those oriignating within the solar circle exit the Galaxy at high latitudes.
