A team from the Faculty of Physics and the Center for Quantum Optical Technologies at the University of Warsaw has developed a new type of all-optical radio receiver based on the fundamental ...

The world’s first all-optical radio runs on laser light, not electricity, opening new possibilities for stealth sensors and ...

Pulsars suggest that ultra–low-frequency gravitational waves are rippling through the cosmos. The signal seen by ...

A new paper presents a method for distinguishing between different sources of nanohertz gravitational waves. Pulsars may be ...

The math of even the simplest ocean waves is notoriously uncooperative. A team of Italian mathematicians has made major ...

Squeezed light is a specialized form of light in which quantum fluctuations are redistributed between two complementary properties. According to quantum theory, light is characterized by ...

Astronomers have witnessed something that no one believed possible: a black hole ripping apart a star not at the center of a ...

Scientists may be coming closer to confirming the existence of dark matter, thought to make up more than one-quarter of the ...

Researchers analyzing pulsar data have found tantalizing hints of ultra-slow gravitational waves. A team from Hirosaki University suggests these signals might carry “beats” — patterns formed by ...

Identifying the gravitational waves from black holes binaries could also make it clearer to detect primordial gravitational ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a ...

For the first time, scientists observed a black hole tearing apart a star far from its galaxy’s center, producing the fastest ...
