‘Missing image’ in gravitational lens systems?

Abstract

The gravitational lens models involving extended mass distribution generally predict an odd number of images with one of the images close to the centre of the principal lensing galaxy. In all the observed lens systems only an even number of images have been unambigously detected so far. It is demonstrated that the presence of a compact nucleus at the centre of lensing galaxies would dim the “odd” image significantly without affecting the rest of the image configuration.
