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.
