Leerdoelen  Engelse vlag By the end of the course the students should: 1. Be able to apply the linearized Einstein equations to compute the approximate gravitational wave signal from various astrophysical sources. 2. Be familiar with the effect of gravitational waves on interferometric detectors. 3. Have a basic working knowledge of techniques to extract weak signals from detector noise, and how to measure parameters related to the source (e.g. masses and spins of binary black holes). 4. Have a broad understanding of how gravitational waves can help in probing issues in fundamental physics, astrophysics, and cosmology. 

Omschrijving  Einstein's theory of general relativity predicts the existence of gravitational waves, which recently were directly detected with the LIGO and Virgo interferometers. The course starts with a recapitulation of the Einstein field equations underlying general relativity. Next it is shown that in the weakfield regime, these can be cast as a wave equation for a field with two independent degrees of freedom, sourced by the energymomentum tensor. Approximate solutions are derived for example astrophysical sources of gravitational waves, such as a fastspinning, asymmetric neutron star, or two compact objects spiraling towards each other. The propagation of gravitational waves on cosmological backgrounds is studied. Finally, it is explained how large interferometers are used to detect gravitational waves, and what signal processing techniques are employed for detecting the signals and extracting information from them. The lectures and tutorials will be placed in the broader context of using gravitational waves to empirically study the fundamental nature of gravity, the structure of neutron stars and black holes, and the largescale evolution of the Universe.
