The Physics Nobel Prize 2017: Gravitational Waves — •Bernd Brügmann — University of Jena

Albert Einstein predicted gravitational waves already hundred years ago as a consequence of his newly formulated theory of general relativity. In highly publicized news, the LIGO/Virgo collaboration announced in 2016 the first direct detection of a gravitational wave signal, and in the end of 2017 the Nobel Prize for Physics was awarded "for decisive contributions to the LIGO detector and the observation of gravitational waves". There is excellent evidence that the first signals correspond to the inspiral and merger of two black holes. Most recently, the first gravitational waves from the collision of two neutron stars have been detected. In this talk we give an overview of the theory and the numerical methods that allow the prediction and analysis of gravitational wave signals. Part of the success story are great advances in numerical general relativity that allow us to simulate binaries with increasing levels of complexity, providing models that explain the observed gravitational wave signals.
