Resolving the Innermost Region of the Accretion Disk of the Lensed Quasar Q2237+0305 through Gravitational Microlensing
We study three high magnification microlensing events, generally recognized as probable caustic crossings, in the optical light curves of the multiply imaged quasar Q2237+0305. We model the light curve of each event as the convolution of a standard thin disk luminosity profile with a straight fold caustic. We also allow for a linear gradient that
