Ciencias de la vida y de la materia Herederos de Galileo

Peter Schneider 21/10/2009

Descripción
Universität Bonn, Bonn, Alemania Madrid, 21 de octubre de 2009 The deflection of light in a gravitational field was not only one of the crucial tests of Einstein's Theory of General Relativity, but has become over the past three decades a highly valuable tool for astronomers and cosmologists. After explaining this gravitational lens effect, I will discuss the various phenomena it creates and what we can learn from them about the mass distribution in galaxies, clusters of galaxies and the large-scale structure of the Universe. Furthermore, I will explain that gravitational lenses are natural -- and cheap -- very powerful telescopes.
