LISA observations of massive black holes binaries using post-Newtonian wave-forms

TL;DR

This paper investigates how incorporating post-Newtonian corrections to both phase and amplitude of waveforms enhances parameter estimation accuracy for massive black hole binaries observed by LISA.

Contribution

It demonstrates that including amplitude corrections in waveforms significantly improves the precision of source parameter extraction.

Findings

Improved parameter estimation accuracy with amplitude-corrected waveforms

Post-Newtonian corrections enhance source localization

Analysis focused on circular, non-spinning black hole binaries

Abstract

We consider LISA observations of in-spiral signals emitted by massive black hole binary systems in circular orbit and with negligible spins. We study the accuracy with which the source parameters can be extracted from the data stream. We show that the use of waveforms retaining post-Newtonian corrections not only to the phase but also the amplitude can drastically improve the estimation of some parameters.
