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 ...

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 ...

To understand why scientists are excited about detecting a new background, just look to the history of studies of the CMB. There’s a new cosmological background in town. In June, researchers from the ...

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 ...
