Relating to Cherenkov radiation, a type of electromagnetic radiation emitted when a charged particle travels through a medium faster than light travels through that same medium.
Named after Soviet physicist Pavel Cherenkov who discovered it in 1934. The phenomenon was explained quantum-mechanically by his colleagues, earning them a Nobel Prize and making his name synonymous with this radiation type.
Cherenkov radiation creates an eerie blue glow in nuclear reactor cooling pools—it's what you see when particles break the cosmic speed limit in water, producing the universe's version of a sonic boom made of light.
