Pulsar timing arrays exploit the extraordinary rotational stability of millisecond pulsars as a network of galactic clocks. By precisely measuring the arrival times of radio pulses over years to ...
When black holes and other enormously massive, dense objects whirl around one another, they send out ripples in space and time called gravitational waves. These waves are one of the few ways we have ...
Pulsar timing enables the most stringent tests of fundamental physics. By monitoring the pulse times of arrival (ToAs) of an ensemble of stable millisecond pulsars (MSPs), known as a pulsar timing ...
A group of Chinese scientists has recently found key evidence for the existence of nanohertz gravitational waves, marking a new era in nanoHertz gravitational wave research. The research was based on ...
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 ...
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 ...
While the scientific community grapples with the loss of the Arecibo radio telescope, astronomers who recently revived a long-dormant radio telescope array in Argentina hope it can help modestly ...
Every 4 milliseconds, a dead star blasts a powerful beam of radiation toward our planet. Don't worry — Earth will be fine. It's the dead star's tiny companion that's in trouble. In a new study ...
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 ...
