How do the universe's highest-energy particles originate? Magnetic outflows stemming from star mergers, analysis concludes

SMRTR summary

Ultrahigh Energy Cosmic Rays (UHECRs) have puzzled scientists for decades. New York University physicist Glennys Farrar proposes that UHECRs are created during neutron star mergers, which form black holes and generate gravitational waves. This theory explains key UHECR features and offers testable predictions, potentially providing new insights into extreme cosmic events and the creation of precious elements like gold and platinum.
