Bounds on the density of sources of ultra-high energy cosmic rays from the Pierre Auger Observatory

We derive lower bounds on the density of sources of ultra-high energy cosmic rays from the lack of significant clustering in the arrival directions of the highest energy events detected at the Pierre Auger Observatory. The density of uniformly distributed sources of equal intrinsic intensity was fou...

description We derive lower bounds on the density of sources of ultra-high energy cosmic rays from the lack of significant clustering in the arrival directions of the highest energy events detected at the Pierre Auger Observatory. The density of uniformly distributed sources of equal intrinsic intensity was found to be larger than similar to (0.06 - 5) x 10⁻⁴ Mp⁻³ at 95% CL, depending on the magnitude of the magnetic defections. Similar bounds, in the range (0.2 - 7) x 10⁻⁴ Mpc⁻³, were obtained for sources following the local matter distribution.
