Astronomers and astrophysicists at five different pulsar timing array collaborations today announced data that strongly suggests the presence of a gravitational wave background: a constant murmur of ...

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by ...

UW-Milwaukee physics and astronomy assistant professor Lia Medeiros explains gravitational waves and the role UWM played in discovering them.

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 ...

Astronomers may have seen the light from two black holes smashing into one another for the first time ever. Black holes are completely dark and therefore invisible to light-detecting telescopes. So ...

Scientists are using pulsars to detect the gravitational wave 'hum' created from supermassive black hole mergers. Credit: ...

Illustration of two black holes orbiting each other. Initially, scientists expected LIGO might detect just a few of these collisions. But now, nearing the first detection’s 10th anniversary, we have ...

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 ...

Einstein's theory of gravity, general relativity, has passed all tests with predictions that are spot-on. One prediction that remains is "gravitational wave memory"—the prediction that a passing ...

Signals buried deep in data from gravitational wave observatories imply a collision of two black holes that were clearly born in different places. Almost all the spacetime ripples that experiments ...

A network of optical cavities could be used to detect gravitational waves (GWs) in an unexplored range of frequencies, according to researchers in the UK. Using technology already within reach, the ...
