Objectifs :
Following this course, the participants will develop a global knowledge of this vast field which has become a subject in itself.

The knowledge acquired will range from planetary perturbation of microlensing events to the analysis of gravitational arcs formed by galaxies and clusters of galaxies.

Some basic competence in the numerical applications associated with gravitational lensing will be also acquired.

Programme :
Gravitational lensing is a very active and highly developed field in astrophysics.

Lensing covers all astrophysical scales from the fine details at the scale of planets around stars to the large scale of cluster of galaxies.

These lectures will offer a global review of all these applications of gravitational lensing. The basic principles and physics for each specific lensing regime will be analyzed in detail. This course will be illustrated by various numerical applications, like ray-tracing, reconstruction of critical lines and caustics, analysis of image properties, and many other applications.

Pré-requis :
Basic mathematics and experience with at least one programming language are prerequisites.

We expect all participants to bring their own laptop.
