Sean Carroll in Preposterous Universe:
The detection of gravitational waves from inspiraling black holes by the LIGO and Virgo collaborations was rightly celebrated as a landmark achievement in physics and astronomy. But ultra-precise ground-based observatories aren’t the only way to detect gravitational waves; we can also search for their imprints on the timing of signals from pulsars scattered throughout our galaxy. Chiara Mingarelli is a member of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) collaboration, which uses pulsar timing to study the universe using gravitational waves.
