Cosmic Telescopes

Séminaire IPAG de Jean-Paul Kneib (LAM Marseille), jeudi 20 octobre 2011 à 11h00, IRAM seminar room

I will review the use of massive galaxy clusters to study the distant Universe. First I will recall the basics of cluster lensing. I will explain how we can build an accurate mass model, and how we can then use these calibrated awkward telescopes to probe distant galaxies. I will present some recent and new results from HST, Herschel and other related observations.
