    QSO 2237+0305 VR Light Curves from Gravitational LensES International Time Project Optical Monitoring
    We present VR observations of QSO 2237+0305 conducted by the Gravitational Lensing International Time Project collaboration from 1999 October 1 to 2000 February...
  • Publication
    QSO size ratios from multiband monitoring of a microlensing high-magnification event
    We introduce a new scheme to study the nature of the central engine in a lensed QSO. The compact emission regions could have different sizes in different...

    Quasar Microlensing Statistics and Flux-ratio Anomalies in Lens Models
    Precise lens modeling is a critical step in time delay studies of multiply imaged quasars, which are key for measuring some important cosmological parameters...

    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...
