Variability of gravitational lens images, caused by variability of gravitational field of lens: binary systems and loops of cosmic strings

Gravitational lenses with changeable mass distribution cause characteristic changes of image brightness. Detection and analyze of such changes allow us to clarify the nature of the lens. This effect gives a possibility to obtain such dynamical objects as loops of cosmic string. In this article we co...
