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

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

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 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 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 ...

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 ...

Since Einstein, physicists have found that certain entities can reach superluminal (that means "faster-than-light") speeds and still follow the cosmic rules laid down by special relativity.
