Impact of using the ultra-high-energy cosmic ray arrival energies to constrain source associations

15 Nov 2018 Francesca Capel Daniel J. Mortlock

We present a Bayesian hierarchical model which enables a joint fit of the ultra-high-energy cosmic ray (UHECR) energy spectrum and arrival directions within the context of a physical model for the UHECR phenomenology. In this way, possible associations with astrophysical source populations can be assessed in a physically and statistically principled manner... (read more)
