On the other hand, Cherenkov radiatiation is only indirectly related to criticality. It comes from any particle moving through a medium, generally water, faster than light travels through that medium. A luminous sonic boom of sorts! It’s associated with criticality because those are the contexts where it happens often enough to actually be visible.
