Precision tests of General Relativity using cosmic clocks — •Michael Kramer — Max-Planck-Institut fuer Radioastronomie

The best tests of theories of gravity for strongly self-gravitating bodies are provided by radio pulsars. Observations of those allow for precision tests of general relativity, all of which have been passed by Einstein's theory with flying colours. In particular in recent years, the exploitation of new systems allowed to probe a wide range of effects, including gravitational wave emission, spin effects, and possible violations of the strong equivalence principle or gravitational Lorentz invariance. Experiments are also ongoing to directly detect low-frequency gravitational waves using regular observations of millisecond pulsars. This talk will review these recent results.
