If a rapidly
spinning black hole merges with a companion, it would produce a unique signal — one that gravitational
wave detectors might be able to
observe, physicist Niels Warburton
An international team of astronomers led by Paulo Freire of the Jodrell Bank Observatory at the University of Manchester, United Kingdom, detected the gas by
observing 15 millisecond pulsars — compact, rapidly
spinning stars that emit bursts of radio
waves with clockwork precision.
