The IceCube project and its preceding AMANDA project used it to detect neutrino interactions with the Antarctic ice cap. Objects which detect this analyze the radii of certain "rings" formed by it, and it can also be observed when the motion occurs over a diffraction pattern, called the Smith-Purcell effect. The magnitude of this can is proportional to the integral over all frequencies of omega times 1 minus 1 over dielectric constant times beta squared, which is known as the Frank Tamm formula.  For 10 points, name this radiation that occurs when charged particles move through a medium faster than the speed of light, named for its Russian discoverer.
