  Cherenkov effect
Cherenkov radiation is electromagnetic radiation emitted when a charged particle passes through an insulator at a velocity greater than the speed of light in that material.
Cherenkov radiation results when a charged particle, most commonly an electron, exceeds the speed of light in a dielectric medium through which it passes.
In nuclear reactors, the intensity of Cherenkov radiation is related to the frequency of the fission events that produce high-energy electrons, and hence is a measure of the intensity of the reaction.

 Pavel A. Cherenkov Biography | World of Physics
Cherenkov was born to peasant parents in the Voronezh region of Russia on July 28, 1904.
Cherenkov was first able to show that the gamma rays produced the same light in a number of different liquids, thus establishing that the light was not affected by the medium through which the high-energy particles passed.
Cherenkov was elected a member of the U.S.S.R. Academy of Sciences in 1970, and he headed the department of high-energy physics of the Lebedev Institute until he died January 6, 1990.

The principal contribution of the Russian physicist Pavel Alekseevich Cherenkov (1904-1990) was the explanation of a certain pale bluish radiation as a consequence of high-speed electrons passing through refractive mediums.
Between 1934 and 1938 Cherenkov conducted a series of intensive investigations of the fluorescence of water bombarded by gamma rays.
Cherenkov and Vavilov, together with Igor Evgenievich Tamm and Ilya Mikhailovich Frank, received the Stalin Prize in 1946 for their explanation, theory, and practical application of the Cherenkov radiation.

Cherenkov discovered that light is emitted by electrons as they pass through a transparent medium at a speed higher than the speed of light in that medium.
Cherenkov graduated from Voronezh State University in 1928; he later became a research student at the P.N. Lebedev Physical Institute of the Academy of Sciences of the Soviet Union (now the Russian Academy of Sciences).
This phenomenon, which was interpreted by Tamm and Frank, led to the development of the Cherenkov counter, or Cherenkov detector, which was later used extensively in experimental nuclear and particle physics.

 Faster than the speed of light travel...Cherenkov radiation - Astronomy.com Forums
Cherenkov radiation (also spelled Cerenkov) is electromagnetic radiation emitted when a charged particle passes through an insulator at a speed greater than that of light in the medium.
In a more complex periodic medium, such as a photonic crystal, one can also obtain a variety of other anomalous Cherenkov effects, such as radiation in a backwards direction (whereas ordinary Cherenkov radiation forms an acute angle with the particle velocity).
In fact, most Cherenkov radiation is in the ultraviolet spectrum - it is only with sufficiently accelerated charges that it even becomes visible; the human eye's sensitivity peaks at green, and is very low in the violet portion of the spectrum.

The emission angle of the light is given by the formula cos(theta)=1/(n*beta), where n is the index of refraction and beta is the particles velocity as a fraction of the speed of light in vacuum, c.
If the momentum of the particle is measured independent and the angle of Cherenkov light emission also reconstructed, then it is possible to derive the mass of the particle.
Often the light is focused with a spherical mirror to reduce the error from the uncertainty in the emission point of the light.

 Is there an equivalent of the sonic boom for light?
The effect known as Cherenkov radiation was observed as a faint blue glow by Pavel Cherenkov in 1934 when he was asked to look at the effects of radioactivity in liquids.
It is possible to detect the Cherenkov radiation as it forms circles on a surface and can be used to measure the speed and direction the particle was travelling in.
Although Cherenkov radiation is indeed a light equivalent of the sonic boom, there are also some essential differences.

Cherenkov radiation derives its name from Pavel Cherenkov, who as a young PhD student at Moscow's Lebedev Institute in the early 1930s, was assigned by Sergei Vavilov the task of investigating what happens to the radiation from a piece of radium when it is immersed in a fluid.
After heroic investigations, where Cherenkov would typically prepare for a working day by staying in a totally dark room for one hour, he found that the radiation was produced by electrons and was essentially independent of the liquid used, thereby ruling out fluorescence.
In 1958, Cherenkov, Frank and Tamm shared the Nobel prize for their work.

When a particle travels faster than the speed of light in water, it produces a shock wave that is the equivalent of a sonic boom made by a jet travelling faster than the speed of sound in air.
This shock wave takes the form of blue light called Cherenkov light, after the Russian physicist Pavel Cherenkov,wall of the detector.
