For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational ...

Einstein's theory of gravity, general relativity, has passed all tests with predictions that are spot-on. One prediction that remains is "gravitational wave memory"—the prediction that a passing ...

The Laser Interferometer Gravitational-wave Observatory (LIGO) and Virgo collaborations first detected gravitational waves in 2015. Ever since, they have continued to unveil new and exciting results ...

Earlier this year, researchers working on the Advanced Laser Interferometer Gravitational-wave Observatory (aLIGO) made the first ever detection of gravitational waves. The waves are believed to have ...

Agilent Technologies Inc. today announced that its PXA signal analyzer is now the industry’s highest performance millimeter-wave signal analyzer, covering frequencies up to 50 GHz. With external ...

The gravitational waves we’ve detected so far have been like tsunamis in the spacetime sea, but it’s believed that gentle ripples should also pervade the universe. Now, a 13-year survey of light from ...

After the historic announcement in February 2016 hailing the discovery of gravitational waves, it didn’t take long for skeptics to emerge. The detection of these feeble undulations in the fabric of ...

Optical millimetre-wave generation and signal processing have emerged as pivotal technologies in modern high-speed communications, advanced radar applications and imaging systems. These techniques ...

A signal generator, a general-purpose piece of test equipment, performs numerous measurements for a variety of applications requiring electromagnetic wave signals as stimuli. Its roots trace back to ...

Last week, astronomers at the Arecibo Observatory in Puerto Rico announced they had picked up some strange radio signals coming from a small red dwarf star, and they couldn’t quite figure out what was ...
