Gravitational waves are ripples in the fabric of spacetime predicted by Albert Einstein’s general theory of relativity, first detected in 2015. But an expected corresponding low-frequency ...

Scientists monitor how ripples in spacetime, most likely caused by the interaction of supermassive black holes, affect the timing of signals from pulsars. (Illustration by Aurore Simonnet for NANOGrav ...

The fabric of the universe is constantly rippling, according to astronomers who have discovered a background buzz of gravitational waves. These waves may be produced by supermassive black holes ...

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 ...

The universe is continuously rippling with gravitational waves, a 15-year survey has reported. Using pulsars as distant beacons and radio telescopes to plumb the galaxy, a massive collaboration of ...

An international collaboration of astrophysicists that includes researchers from Yale has created and tested a detection system that uses gravitational waves to map out the locations of merging black ...

Astronomers have found the strongest evidence yet for a predicted-yet-undetected class of gravitational waves created by supermassive black holes in the cores of galaxies. And they think they could ...

In February 2016, Gravitational Waves (GWs) were detected for the first time in history. This discovery confirmed a prediction made by Albert Einstein over a century ago and triggered a revolution in ...
