High-accuracy waveforms for black hole-neutron star systems

The observation of gravitational waves (GWs) relies on accurate analytical waveform models. These models are also necessary for parameter estimation of the two astronomical bodies that comprise compact binaries. The production of such analytical waveform models for GW astrophysics depends on whether or not accurate numerical waveforms are available for public use. For black hole-neutron star (BHNS) merger events, there is an absence of publicly available accurate numerical waveforms. The increase in the sensitivity of GW interferometers will inevitably bring about additional detections of BHNS binary merger events. In this talk, I summarize a number of long, accurate numerical BHNS waveforms produced via the spectral Einstein code (SpEC) to better span the binary parameter space of potential BHNS merger configurations. These waveforms are publicly available as part of the Simulating eXtreme Spacetimes (SxS) collaboration’s catalog.
