“Detecting Violations of General Relativity: Weak and Strong Field”

To date General Relativity (GR) remains the most successful theory describing gravity, passing tests conducted in laboratory experiments, the solar system, binary pulsars, and on cosmological scales. Still, even after a century of such tests, an important goal of physics remains to predict and verify consequences of possible alternatives to GR. One reason for these continued tests is that deviations from GR could be a signature of a more fundamental theory. In this talk, an overview of weak-field and strong-field tests will be discussed, with an example of a specific alternative theory and current tests offering raw data in the near future. I will also discuss current work that focuses on an asymptotic expansion method for error estimation. The estimation technique targets parameters modifying gravitational waveforms, measured in a global network of advanced gravitational wave detectors.
