Science, 1989
Several instances of multiple imaging of cosmologically distant sources by intervening galaxies and galaxy clusters have been discovered over the past decade. These "gravitational lenses" have distinctive optical properties. Pointlike sources such as quasars generally produce two or four images when lensed, whereas extended sources such as galaxies ...

A plastic lens is described which will bend light rays parallel to the lens axis in the same way as a static (Schwarzschild) gravitational field. This allows one to observe the optical distortions caused by a (nonrotating) black hole directly. The double-imaging property is discussed with particular application to the recently announced double quasar ...

GRAVITATIONAL LENS AMPLIFICATION OF GRAVITATIONAL RADIATION
International Journal of Modern Physics D, 2002In a recent paper by Wang, Turner and Stebbins (1996) an influence of gravitational lensing on increasing an estimated rate of gravitational radiation sources was considered. We show that the authors used the geometrical optics approximation model for gravitational lensing and thus they gave overestimated rate of possible events for possible sources ...

Gravitational Self-Lens Effect
Physical Review D, 1973The optical image of a luminous mass under the influence of its own gravitational field near the Schwarzschild radius, as in the case of a dense neutron star, is studied. It is found that two important deviations from the classical nonrelativistic behavior occur. First, the stellar body appears to be enlarged by a gravitational self-lens effect. In the
