By combining subtle distortions in spacetime with observations of unusually bright galactic centers, the study authors have ...

Astronomers just discovered a background “hum” of low-frequency gravitational waves constantly rippling through the universe — but what’s next? When two galaxies merge, the supermassive black holes at ...

An international collaboration of astrophysicists that includes researchers from Yale has created and tested a detection ...

The gravitational waves we’ve detected so far have been like tsunamis in the spacetime sea, but it’s believed that gentle ripples should also pervade the universe. Now, a 13-year survey of light from ...

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 ...

Things are about to change in a supermassive way in the world of astrophysics. An international team of scientists have discovered evidence for a new type of signal they have long searched for—one ...
