Description

The future gravitational wave observations of the Laser Interferometer Space Antenna (LISA) mission have a huge scientific potential to test General Relativity. The key to unlocking such potential is to develop accurate and fast beyond vacuum waveforms and an efficient data analysis pipeline. This talk will illustrate how to do this with Extreme Mass Ratio Inspiral (EMRI) systems. We will present a full Bayesian analysis to test General Relativity with EMRI systems endowed with a scalar field. We will show that observing a "golden" EMRI can constrain the scalar charge tighter than ground-based gravitational wave detectors. Finally, we will outline the key challenges we will face when testing General Relativity with LISA data.
