Using a detector the size of a galaxy, astronomers find strongest evidence yet for gravitational waves from supermassive black hole pairs

Daniel Reardon, Swinburne University of Technology and Andrew Zic, CSIRO

By timing radio pulses from an array of galactic pulsars, scientists see hints of gravitational waves from supermassive black hole pairs in a breakthrough that may reveal hidden details of galaxy evolution.
