Description
We explore the eccentricity detection threshold of the future space-based mission LISA for gravitational waves (GWs) radiated by massive black hole binaries (MBHBs) with BH masses in the range $10^4$--$10^6~{\rm M}_\odot$ at redshift $z=1$. We will generate mock high-order post-Newtonian eccentric waveforms, project them in LISA arms to perform time delay interferometry to cancel laser noise, and use both Fisher and Bayesian inference via MCMC to see how well we can constrain injected parameters as a function of the waveform's signal-to-noise ratio. This study is much needed as eccentricity can be a unique tracer of the environment where these MBHBs evolve to reach the merger phase in the LISA band.
