Installation of in-vacuum equipment as a part of the squeezed-light upgrade before Advanced LIGO’s third observing run. LIGO team members install in-vacuum equipment that is part of the squeezed-light ...

PASADENA, Calif.– The Advanced LIGO Project, an upgrade in sensitivity for LIGO (Laser Interferometer Gravitational-wave Observatories), was approved by the National Science Board in its meeting on ...

Researchers have demonstrated a new, unsupervised machine learning approach to find new patterns in the auxiliary channel data of the Laser Interferometer Gravitational-Wave Observatory. Finding ...

On Sept. 14, 2015, physicists attained the long-sought goal of detecting gravitational waves, the shockwaves spewed out by such cataclysmic events as the violent merger of two black holes. Now, in the ...

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, ...

Since the first direct detection of gravitational waves by the LIGO detectors on September 14, 2015, the main hoopla has (justifiably!) been about how the results support Einstein's Theory of General ...

By investigating the interference pattern — the way the peaks and troughs of the light waves combine — scientists can determine if a gravitational ripple happened during the experiment. If so, they ...

The Trump administration wants to close one of the nation's two cutting-edge observatories - one of them in the Tri-Cities - that made scientific history and launched a new way to study the universe.

A look at the technology that creates squeezed light in LIGO's vacuum chamber. The picture was taken from one of the chamber's viewports at a time when the squeezer was operational and pumped with ...
