 要：We propose that ultrahigh energy cosmic rays are produced in binary 
 neutron star mergers.  This scenario can account for the heretofore inexp
 licable narrow rigidity range of UHECRs\, because the jets of BNS mergers 
 are generated by a gravitationally-driven dynamo and thus are nearly ident
 ical due to the narrow range of BNS masses.  Observed UHECRs with energie
 s well beyond 100 EeV can be explained as r-process nuclei\, without invok
 ing an exotic source class.  Evidence for this mechanism\, and its predic
 tion of coincidences between neutrinos above 10 PeV and gravitational wave
 s\, are discussed.\n\nhttps://indico.nitep.osaka-cu.ac.jp/event/174/
