Title

Impact Of The Gravitational Radiation Higher Modes in Aligned Spin Searches For Binary Black Holes
Coauthors

Abstract

Current gravitational wave searches for compact binaries neglect the higher order harmonics of the emitted radiation. Several studies have demonstrated that this neglection has an important impact in terms of event loss and parameter bias on high mass non-spinning searches and in the context of the design version of Advanced LIGO. We extend these studies to the case of single-aligned spin searches for both the design Advanced LIGO and the upcoming early Advanced LIGO, which will come online this year and whose different sensitivity crucially enhances the effect of higher order modes. We also study the case of the initial LIGO detector in the context of a non-spinning search.

Title

Accuracy of Complete Hybrid PN/NR Descriptions Of The Gravitational Radiation From Non-Precessing Compact Binaries
Coauthors

Abstract

Hybrid post-Newtonian/Numerical Relativity (PN/NR) waveforms are the basis of continuous inspiral-merger-ringdown waveform families like the several Phenom families and have been used as models of the true emitted signal in several mock data challenges. However, up to now, these have only included the dominant mode of the GW emission. We discuss the construction of hybrid PN/NR waveforms including the higher order modes of the gravitational radiation emitted by non-precessing compact binaries and analyze the accuracy with which these are computed in the context of both the PN and NR formalisms. We find that PN results are mainly affected by truncation errors while NR ones have their main error source in the finitude of the radius at which the signal is extracted. We show results obtained using both BAM and SpEC NR data and provide figures of merit and diagnostics of the quality of the final full hybrid waveform.
