- W2592955320 abstract "The planned Laser Interferometer Space Antenna (LISA) is expected to detect the inspiral and merger of massive black hole binaries (MBHBs) at $zensuremath{lesssim}5$ with signal-to-noise ratios (SNRs) of hundreds to thousands. Because of these high SNRs, and because these SNRs accrete over periods of weeks to months, it should be possible to extract the physical parameters of these systems with high accuracy; for instance, for a $ensuremath{sim}{10}^{6}{M}_{ensuremath{bigodot}}$ MBHBs at $z=1$ it should be possible to determine the two masses to $ensuremath{sim}0.1%$ and the sky location to $ensuremath{sim}1ifmmode^circelsetextdegreefi{}$. However, those are just the errors due to noise: there will be additional ``theoretical'' errors due to inaccuracies in our best model waveforms, which are still only approximate. The goal of this paper is to estimate the typical magnitude of these theoretical errors. We develop mathematical tools for this purpose, and apply them to a somewhat simplified version of the MBHB problem, in which we consider just the inspiral part of the waveform and neglect spin-induced precession, eccentricity, and PN amplitude corrections. For this simplified version, we estimate that theoretical uncertainties in sky position will typically be $ensuremath{sim}1ifmmode^circelsetextdegreefi{}$, i.e., comparable to the statistical uncertainty. For the mass and spin parameters, our results suggest that while theoretical errors will be rather small absolutely, they could still dominate over statistical errors (by roughly an order of magnitude) for the strongest sources. The tools developed here should be useful for estimating the magnitude of theoretical errors in many other problems in gravitational-wave astronomy." @default.
