Anticipation Builds for Groundbreaking Gravitational Wave Discovery Announcement

The North American Nanohertz Observatory for Gravitational Waves (NANOGrav) is set to make a major announcement on June 29, 2023, regarding research conducted by the International Pulsar Timing Array. The announcement is expected to shed light on the search for the gravitational wave background, a random or 'stochastic' buzz of gravitational waves produced by the hum of many weak, independent, and unresolved astrophysical sources. The detection of the gravitational wave background could provide a wealth of information about astrophysical source populations and processes in the very early Universe, which are not accessible by any other means.
