Gravitational lensing is used to determine the masses of lensing galaxies and clusters and to study more distant galaxies that can be magnified by a factor of more than 20.
Typically, the target systems correspond to lensing of z > 0.5 star-forming galaxies by luminous red galaxies and brightest cluster galaxies.
