Xth School of Cosmology in Cargese: Gravitational Lenses

Main topics:
– Weak gravitational lensing (a tool to find the equation of state of dark energy).
– Lensing galaxy clusters, the distribution of dark matter.
– Strong gravitational lensing by galaxy clusters, and study the first galaxies at high resolution.
– Extragalactic gravitational microlensing (quasars and dark matter).
– Galaxy-galaxy gravitational lensing.
