Ultrahigh-energy cosmic-ray nuclei and neutrinos from engine-driven supernovae
Ultrahigh-energy cosmic-ray nuclei and neutrinos from engine-driven supernovae
Transrelativistic supernovae (SNe), which are likely driven by central engines via jets or winds, have been among the candidate sources of ultrahigh-energy cosmic rays (UHECRs). We investigate the acceleration and survival of UHECR nuclei in the external reverse shock scenario. With the composition models used in Zhang et al., [Phys. …
