Using gravitational wave detectors LIGO, Virgo, and KAGRA, scientists have identified a 'stellar graveyard' filled with mergers of black holes and neutron stars, including the heaviest black holes observed to date, which enhances understanding of stellar evolution and the universe's expansion rate. The data also tests Einstein's theory of gravity and improves measurement of the Hubble Constant.

A new study proposes that the most energetic cosmic rays are generated during the magnetic chaos of merging neutron stars just before they collapse into black holes, potentially explaining their extreme energies and linking them to gravitational wave events and neutrino bursts. This model offers a testable hypothesis that could unify observations of cosmic rays, gravitational waves, and neutrinos, advancing our understanding of high-energy astrophysical phenomena.
