General relativity is one of the most successful theories mankind has ever developed, but one of its predictions—the existence of gravity waves—has never been confirmed. Gravity waves are analogous to ...
As an international collaboration of radio astronomers from Australia, Germany, the UK, South Africa, the Netherlands, Italy and France, the MeerKAT Pulsar Timing Array (MPTA) has created a ...
The universe is humming with gravitational radiation — a very low-frequency rumble that rhythmically stretches and compresses spacetime and the matter embedded in it. That is the conclusion of several ...
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 ...
Infrared cosmos: the cosmic infrared background at 857 GHz as seen by the European Space Agency's Planck mission. (Courtesy: ESA/Planck) Physicists in the UK and the US have shown how to use one kind ...
Gravitational waves from inflation generate a faint but distinctive twisting pattern in the polarization of the cosmic microwave background, known as a "curl" or B-mode pattern. For the density ...
An Alfvén-wave maser, a feature of atmospheric and astrophysical science, has been created in a laboratory, and opens the way for further Earth-bound investigations of cosmic phenomena. For some years ...
LIGO confirmed the existence of gravitational waves in 2015, detecting one-time perturbations of spacetime from the merger of large black holes. There should be a background of gravitational waves ...
Artist’s interpretation of an array of pulsars being affected by gravitational ripples produced by a supermassive black hole binary in a distant galaxy. CREDIT Aurore Simonnet for the NANOGrav ...
