The Project is aimed at using the power of gravitational lenses to address several important aspects of Extragalactic Astrophysics/Cosmology.
We use the broad experience of our group in theory, observations, and modeling of gravitational lenses with the following aims:
Estimate the dark matter content of the Universe (in particular in the form of primordial black holes).
Probe CDM or alternative models from the effects of dark matter substructure on the images of lensed quasars (millilensing).
Study the accretion disk and BLR structure and kinematics (in particular the Fe II and III emission regions) from microlensing induced variability on the emission line profiles.
Use the gravitational redshift of the Fe III UV to determine the masses of the quasars central supermassive black holes.
Study lensed quasar hosts from spectroastrometry.
Develop new numerical and statistical methods to study microlensing.
