Microlensing and the size of the engine

Optical monitoring of multiply lensed quasars allows to constrain the size of the quasar continuum emitting region through the amount of variability due to gravitational microlensing. We show results from our decade-long monitoring program at Las Cumbres Observatory, highlighting differences of the light curve variability from quasar to quasar, and discussing the implications for the source size. The impact of other potentially contributing effects will be discussed.
