Astronomers find possible 'fingerprints' of gravitational waves

Astronomers using data collected by our Parkes radio telescope, Murriyang, have found their strongest evidence yet for low-frequency gravitational waves.

For nearly 20 years the Parkes Pulsar Timing Array collaboration has monitored a set of pulsars, looking for nanosecond pulse delays caused by gravitational waves. By compiling and analysing this large data set, the team has taken another step towards detecting gravitational waves through the study of pulsars.

Their latest results have been published today in The Astrophysical Journal Letters and Publications of the Astronomical Society of Australia.
