Possible Connection Found Between Neutron Star Collision and Fast Radio Burst
The Canadian Hydrogen Intensity Mapping Experiment (CHIME) recorded a bright, non-repeating fast radio burst (FRB) on April 25, 2019, just 2.5 hours after the Laser Interferometer Gravitational-Wave Observatory (LIGO) recorded a gravitational wave event. The FRB's location in the sky fell within the credible region of the gravitational wave event, and from a similar distance. The chance that the two events were unrelated is extremely small. The researchers believe that the burst was caused by a blitzar, a mechanism proposed for FRBs nearly a decade ago, and the two events likely emerged from a galaxy called UGC 10667.
