Estimado/as
Jueves 01 de Julio a las 12:15 hrs, tendremos seminario en el Departamento de Astronomía de la Universidad de Chile.
Speaker: Felipe Asenjo Zapata
Facultad de Ingeniería y Ciencias
Universidad Adolfo Ibáñez
Title: The effect of gravity on light propagation beyond eikonal approximation
Abstract: Gravity interacts with light by, for instance, curving its trajectory or shifting its frequency. These are the well-known gravitational lensing and cosmological redshift effects. However, on the calculation of such effects it is used the eikonal approximation. This models light as a massless particle travelling in ray paths. When we go beyond that approximation, new effects emerge because the extended (wave) nature of light. In this talk, we will discuss how curved spacetimes can couple to polarization of electromagnetic waves, or even modify its propagation to non-null geodesics.
