Detection method

Pulsar Timing Array

Using an array of millisecond pulsars — nature's most precise clocks — as a galaxy-sized gravitational-wave detector. A passing nanohertz gravitational wave subtly shifts the arrival times of the pulsars' pulses in a correlated way; timing arrays have found evidence for a background of such waves from supermassive black-hole binaries.
