Descripción
Simple gravitational lens models usually suffice to reproduce the
positions of lensed quasar images, but they have problems to reproduce
their optical flux ratios. The so-called flux ratio anomalies are
thought to be produced by small-scale structure in the lens galaxies
(microlensing).
