A 'boom' of light that appears when a particle exceeds the speed of light set by a medium could, in other contexts, signal a ...

Cherenkov radiation refers to the photon emission from the swift charged particle moves with the velocity greater than the phase velocity of light in the surrounding materials. Ever since its ...

Cherenkov light appears when a charged particle travels through matter faster than light can. This effect is the optical equivalent of a sonic boom, which occurs, for example, when a jet travels ...

Cherenkov radiation, the faint blue glow produced when charged particles exceed the phase velocity of light in a dielectric medium, has rapidly evolved from a fundamental physical phenomenon to a ...

Flashes like Cherenkov radiation in space may reveal negative-energy ghosts, hinting at gaps in gravity theories.

An array of photomultiplier tubes, used to detect faint sources of light, mounted inside the steel tank of the Eos detector. The photomultiplier tubes will eventually be submerged in water admixed ...

On 15 December, the Large-Sized Telescope (LST) Collaboration announced through an Astronomer's Telegram (ATel) the detection of the source OP 313 at very high energies with the LST-1. Although OP 313 ...

The glow from faster-than-light particles gives us a unique way to explore the universe. Nothing can travel faster than light — in a vacuum. But when light slows down, sometimes matter can blaze past ...
