Gravitational Lenses

Lecturer: Dr. André Zamorano Vitorelli, PhD (NASA/JPL)

Schedule: July 15 to July 19 (5 classes), all at 10h00 (BRT)/13h00 (UTC). One must attend at least 4 classes to receive a certificate.

Workload: 10h

Topics: 1. Introduction, history, propagation of light in curved spaces. 2. Study of the lens equation and its consequences. 3. Strong gravitational lenses: gravitational arcs, supernovae and multiple imaging, microlenses. 4. Weak gravitational lenses: galaxy clusters, galaxy-galaxy. 5. Short review of cosmology, cosmic shear, open problems.

Pre-requisites: A standard introductory course in general relativity.
