Precise lens modeling is a critical step in time delay studies of multiply imaged quasars, which are key for measuring some important cosmological parameters...

We propose and discuss a new experimental approach to measure the centroid shift induced by gravitational microlensing in the images of lensed quasars...

We show that quasar microlensing magnification statistics induced by a population of point microlenses distributed according to a mass spectrum can be very well...
