An improved effective-one-body model of spinning, nonprecessing binary black holes for the era of gravitational-wave astrophysics with advanced detectors

Alejandro Bohé, Lijing Shao, Andrea Taracchini +17

We improve the accuracy of the effective-one-body (EOB) waveforms that were employed during the first observing run of Advanced LIGO for binaries of spinning, nonprecessing black h…

Complete waveform model for compact binaries on eccentric orbits

E. A. Huerta, Prayush Kumar, Bhanu Agarwal +11

We present a time domain waveform model that describes the inspiral-merger-ringdown (IMR) of compact binary systems whose components are non-spinning, and which evolve on orbits wi…
