Researchers at TU Wien and UC San Diego have created the first continuously tunable X-ray harmonic source, sliding smoothly ...

Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how electrons dance together. The technique, known as X-ray four-wave mixing, ...

Astronomers from the International Center for Radio Astronomy Research (ICRAR), in collaboration with international teams, have made a startling discovery about a new type of cosmic phenomenon. The ...

Everything on the electromagnetic spectrum has some properties of both waves and particles, but it’s difficult to imagine a radio wave, for example, behaving like a particle. The main evidence for a ...

Researchers at the CUNY Advanced Science Research Center have shown that waves inside irregularly shaped cavities made of ...

A team of international astronomers have discovered a new cosmic object emitting both radio waves and x-rays. Astronomers from the International Centre for Radio Astronomy Research (ICRAR), in ...
