Researchers report a significant advance in quantum squeezing, which allows them to measure undulations in space-time across the entire range of gravitational frequencies detected by LIGO. In 2015, ...

FROnt Surface Type Irradiator, or FROSTI, will allow future detectors to run at higher laser powers, reducing noise and expanding capabilities ...

Subtract that common signal, and what is left is residual noise unique to each detector at any moment, because its seismic vibrations and so on constantly vary. This is LIGO’s main ploy for extracting ...

LIGO, the Laser Interferometer Gravitational-wave Observatory, has been called the most precise ruler in the world for its ability to measure motions more than 10,000 times smaller than the width of a ...

New results from an international team including UBC astrophysicists highlight the first black hole observed to be spinning ...

In January 2025, a ripple in spacetime reached Earth from more than a billion light-years away. It wasn’t light or radio ...

Gravitational wave facilities measure distortions in the fabric of spacetime down to 10 quadrillionths the width of a hair – small enough to hear interference from particles popping in and out of ...

After a three-year hiatus, scientists in the U.S. have just turned on detectors capable of measuring gravitational waves—tiny ripples in space itself that travel through the universe. Unlike light ...

New mirror coatings will increase the volume of space LIGO can probe in its next run. Since LIGO's groundbreaking detection, in 2015, of gravitational waves produced by a pair of colliding black holes ...

Quantum mechanics usually applies to very small objects: atoms, electrons and the like. But physicists have now brought the equivalent of a 10-kilogram object to the edge of the quantum realm.
