Laboratoire Astrophysique de Marseille (LAM)

Chapitres

  1. Introduction on strong lensing & the key features used for probing the high redshift Universe
  2. Strong lensing modeling techniques
  3. Counting lensed galaxies
  4. Probing z>6 lensed galaxies

Résumé

In these 2 lectures, I will present the topic of strong lensing and how it can be used to probe the high redshift Universe. I will start with an introduction of strong lensing and its key features in studying the distant Universe: magnification and source plane dilution. I will then explain how we do model strong lensing system with a detailed discussion of the constraints and the different techniques used. I will then explain how strong lensing has been used to count lensed galaxies and how we can uses lenses to probe the high redshift z>6 universe.
