Descripción
Multiple images of QSOs are formed when the gravitational field of an
intervening galaxy bends the trajectories of the light rays. The
granulation of the lens galaxy mass distribution (either in stars or
compact dark matter objects) could induce non correlated variability
between different images of the lensed QSO (microlensing). The relevance
of microlensing depends on the source size and, on light of some recent
results, could affect to the Broad Emission Lines of QSOs. In this
contribution we review the effects on the BLR of microlensing by an
isolated microlens, a straight fold caustic and a caustic network.
