World-wide Radio Telescope Network Strengthens Evidence for Signal that May Hint at Ultra-Low Frequency Gravitational Waves

An international team of astronomers, including members of the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), has announced the results of a comprehensive search for ripples in the fabric of space-time – known as gravitational waves. The team searched for low-frequency gravitational waves, which can originate from supermassive black hole binaries residing in galaxies or from events occurring soon after the formation of the universe in the Big Bang. Detecting these low-frequency signals will open a brand-new window in the gravitational wave spectrum and help scientists enhance their understanding of the evolution of galaxies, their central black holes, and the early universe.

NANOGrav & Green Bank Telescope Poised to Make Groundbreaking Discoveries of Gravitational Wave Universe

For the next three years, astronomers from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) will have increased access and new technologies to use on the National Science Foundation’s Green Bank Telescope (GBT) in their breakthrough scientific studies of gravitational waves. This new technology and additional observation time is supported by funding from the Moore Foundation.
