The passing gravitational waves “stretch or contract the universe by around 20 meters [about 65 feet] or so,” says Matthew ...

LISA is set to revolutionize our understanding of the gravitational universe and the interactions that make the entire cosmos ...

Software engineers have been hard at work to establish a common language for a global conversation. The topic—revealing the ...

We can't help ourselves but wonder about life elsewhere in the universe. Any hint of a biosignature or even a faint, ...

Abstract: The performance tradeoffs required for a small satellite synthetic aperture radar (SAR) system designed to measure surface deformations using persistent scatterer interferometry (PSI) are ...

Current atomic interferometers rely on nanomechanical membranes, but increased momentum transfer via crystal gratings could make interferometers even more sensitive. On September 14, 2015 ...

Abstract: A phase generated carrier (PGC) demodulation system for fiber Bragg grating (FBG) time-domain multiplexed accelerometers array is proposed. To eliminate environmental noise effect on the ...

The SMA is a type of multiple-antenna observatory known as an interferometer, in this case consisting of eight radio dishes, each 6 meters in diameter. The eight antennas observe the same astronomical ...
