Influence of Plasma on Relativistic Images of Gravitational Lensing
O. Yu. Tsupko and G. S. Bisnovatyi–Kogan

In presence of plasma the gravitational lensing is chromatic. Even in the homogeneous plasma the gravitational deflection differs from the vacuum deflection angle, and the gravitational deflection angle in plasma depends on the frequency of a photon. We discuss influence of plasma on relativistic images formed by photons which perform one or several turns around the lens.


Key words: gravitational lensing, plasma
