Effects of waveform model systematics on the interpretation of GW150914

The LIGO Scientific Collaboration, the Virgo Collaboration, B. P. Abbott +999

Parameter estimates of GW150914 were obtained using Bayesian inference, based on three semi-analytic waveform models for binary black hole coalescences. These waveform models diffe…

Saturating The Bekenstein-Hawking Entropy Bound With Initial Data Sets For Gravitational Collapse

Sina Bahrami

It is possible to find initial states for gravitational collapse whose entropy approximately saturates the Bekenstein-Hawking entropy of the final black hole. The prototypical exam…

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…

Second-order perturbation theory: the problem of infinite mode coupling

Jeremy Miller, Barry Wardell, Adam Pound

Second-order self-force computations, which will be essential in modeling extreme-mass-ratio inspirals, involve two major new difficulties that were not present at first order. One…
