Predicted by Einstein and dismissed as undetectable, gravitational waves were finally heard in 2016. Now, with observatories ...

In this letter, a multimode antenna for adaptive space-division multiple access (SDMA) application is proposed. The antenna merges a monopole-like radiator and a multimode resonant cavity into a ...

NASA was to supply some critical technologies for the mission, which Europe may not be able to readily replace.

A laser interferometer employing a reference arm with a spherical mirror is discussed. This interferometer is extremely promising in many fields of scientific endeavor, for instance, in plasma physics ...

Astronomers confirm ‘lite intermediate’ black holes, too large for ordinary stars, revealing clues about early stellar origins.

Researchers aim to explore hidden aspects of the universe that could fundamentally transform our understanding of the cosmos ...

Similar to gravitational observatories on Earth, the laser light is the crucial component of the detector. Gravitational ...

With LISA, ESA plans to catch gravitational waves from space, using a triangle of spacecraft millions of kilometers ...
