Abstract

The future space-based gravitational wave observatory, the Laser Interferometer Space Antenna, is expected to observe between a few and a few thousand extreme mass-ratio inspirals (EMRIs) per year. Due to the simultaneous presence of other gravitational wave signals in the data, it can be challenging to detect EMRIs and accurately estimate their parameters. In this work, we investigate the interaction between a gravitational signal from an EMRI and millions of signals from inspiralling Galactic white dwarf binaries. We demonstrate that bright Galactic binaries contaminate the detection and characterization of EMRIs. We perform Bayesian inference of EMRI parameters after removing resolvable Galactic binaries and confirm an accuracy comparable to that expected in Gaussian noise.
