In gravitational-wave astronomy, observations of gravitational waves are used to infer data about the sources of gravitational waves. Sources that can be studied this way include binary star systems composed of white dwarfs , neutron stars , [ 8 ] [ 9 ] and black holes ; events such as supernovae ; and the formation of the early universe ...

Gravitational waves were first predicted in 1916 by Einstein, who was trying to understand how gravity moves in the cosmos. Learn about gravitational waves and how a Tri-Cities observatory spots ...
Scientists on Wednesday unveiled evidence that gravitational waves, the ripples in the fabric of space-time predicted by Albert Einstein more than a century ago, are permeating the universe at low ...
A new window on the universe was opened when gravitational waves were detected for first time from the collision of two black holes in 2015. Exploding stars and gravitational waves is topic at May ...
In gravitational-wave astronomy, observations of gravitational waves are used to infer data about the sources of gravitational waves. Sources that can be studied this way include binary star systems composed of white dwarfs , neutron stars , and black holes ; events such as supernovae ; and the formation of the early universe shortly after the ...
The NANOGrav team wrote that "The observation of Hellings–Downs correlations points to the gravitational-wave origin of this signal." [3] The Hellings-Downs curve has also been referred to as the "smoking gun" [6] or "fingerprint" [15] of the gravitational-wave background. These examples highlight the critical role that the Hellings-Downs ...
First discovered in 2015 by the Laser Interferometer Gravitational-Wave Observatory, or LIGO, gravitational waves are physical ripples in spacetime caused by objects with mass moving through space ...
