Abstract
A covariant criterion for the emission of Cherenkov radiation in the field of a nonlinear gravitational wave is considered within the framework of exa ct integrable models of particle dynamics and electromagnetic wave propagat ion. It is shown that a vacuum interacting with curvature can give rise to Cherenkov radiation. The conically shaped spatial distribution of radiation is derived and its basic properties are discussed.
