North American Nanohertz Observatory for Gravitational Waves

The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) is a scientific collaboration dedicated to the detection and study of gravitational waves in the nanohertz frequency range. This observatory primarily focuses on using pulsar timing observations to detect these gravitational waves, which are ripples in spacetime caused by massive astronomical events such as the merger of supermassive black holes.
