Gravitational Lensing

Variable Universe

Variable stars, RR Lyrae, transients, supernovae, microlensing events.

Gravitational Lensing

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.

CASSOWARY

Typically, the target systems correspond to lensing of z > 0.5 star-forming galaxies by luminous red galaxies and brightest cluster galaxies.
