Gravitational wave search no humdrum hunt 28 May 2021 The gentle hum of a spinning neutron star is very faint and almost impossible to detect The hunt for the never before heard "hum" of gravitational waves caused by mysterious neutron stars has just got a lot easier, thanks to an international team of researchers. Gravitational waves have only been detected from black holes and neutron stars colliding, major cosmic events that cause huge bursts that ripple through space and time. The research team, involving scientists from the LIGO Scientific Collaboration (LSC), Virgo Collaboration and the Centre for Gravitational Astrophysics (CGA) at The Australian National University (ANU), are now turning their eagle eye to spinning neutron stars to detect the waves.
