The curious case of the maximum rigidity distribution of cosmic-ray accelerators

Although astrophysical accelerators of ultra-high-energy cosmic rays (UHECR) must be intrinsically diverse, our simulations of a diverse source population show that the UHECR data can only be fit if UHECR sources are intrinsically almost identical.
