The newly detected gravitational wave background could be the result of supermassive black hole binaries that orbit each other for a few million years before merging. By now you’ll have seen the news ...

Researchers have found the first direct evidence of a “background” of gravitational waves in the universe — a sign that gravitational waves from slowly merging pairs of supermassive black holes, or ...

Researchers just announced the discovery of the gravitational wave background. After a 15-year-long study, the scientists have finally “heard” what they were looking for: the gravitational waves that ...

The results of a comprehensive search for a background of ultra-low frequency gravitational waves has been announced by an international team of astronomers. The results of a comprehensive search for ...

According to the general theory of relativity, gravitational waves are produced by accelerating mass distributions with a quadrupole (or higher) moment. Moreover, in the early phases of the evolution ...

Cosmic claims: researchers have used radio telescopes around the world to hunt for gravitational waves using the subtle variations in the timing of pulsars. (Courtesy: Aurore Simonnet for the NANOGrav ...
