Estimating parameters of BH-NS binaries with gravitational waves

ORAL

Abstract

Ground-based gravitational wave detectors will soon identify the gravitational wave signal from merging stellar-mass compact binaries, including black hole-neutron star (BH-NS) binaries. With their mass ratio and spin, BH-NS binaries produce an intrinsically complicated multimodal signal. In this talk, we examine how well gravitational wave detectors can estimate the parameters of fiducial nonprecessing and precessing binaries. We compare our detailed Markov-chain Monte Carlo simulations against analytic (Fisher matrix) calculations.
