Complete phenomenological gravitational waveforms from spinning coalescing binaries
R. Sturani, S. Fischetti, L. Cadonati +4
The quest for gravitational waves from coalescing binaries is customarily performed by the LIGO-Virgo collaboration via matched filtering, which requires a detailed knowledge of th…
Eccentricity estimation for five binary black hole mergers with higher-order gravitational wave modes
H. L. Iglesias, J. Lange, I. Bartos +9
The detection of orbital eccentricity for a binary black hole system via gravitational waves is a key signature to distinguish between the possible binary origins. The identificati…
Unequal Mass Binary Black Hole Plunges and Gravitational Recoil
F. Herrmann, I. Hinder, D. Shoemaker +1
We present results from fully nonlinear simulations of unequal mass binary black holes plunging from close separations well inside the innermost stable circular orbit with mass rat…
Impact of densitized lapse slicings on evolutions of a wobbling black hole
U. Sperhake, K. L. Smith, B. Kelly +2
We present long-term stable and second-order convergent evolutions of an excised wobbling black hole. Our results clearly demonstrate that the use of a densitized lapse function ex…
Efficient asymptotic frame selection for binary black hole spacetimes using asymptotic radiation
R. O'Shaughnessy, B. Vaishnav, J. Healy +2
Previous studies have demonstrated that gravitational radiation reliably encodes information about the natural emission direction of the source (e.g., the orbital plane). In this p…
Boosted three-dimensional black-hole evolutions with singularity excision
The Binary Black Hole Grand Challenge Alliance, :, G. B. Cook +43
Binary black hole interactions provide potentially the strongest source of gravitational radiation for detectors currently under development. We present some results from the Binar…
The NINJA-2 project: Detecting and characterizing gravitational waveforms modelled using numerical binary black hole simulations
The LIGO Scientific Collaboration, the Virgo Collaboration, 2 Collaboration +888
The Numerical INJection Analysis (NINJA) project is a collaborative effort between members of the numerical relativity and gravitational-wave astrophysics communities. The purpose…
Is J enough? Comparison of gravitational waves emitted along the total angular momentum direction with other preferred orientations
R. O'Shaughnessy, J. Healy, L. London +2
The gravitational wave signature emitted from a merging binary depends on the orientation of an observer relative to the binary. Previous studies suggest that emission along the to…
Ultra-High-Energy Cosmic Rays: The Intersection of the Cosmic and Energy Frontiers
A. Coleman, J. Eser, E. Mayotte +95
The present white paper is submitted as part of the "Snowmass" process to help inform the long-term plans of the United States Department of Energy and the National Science Foundat…
Environmental Noise in Advanced LIGO Detectors
P. Nguyen, R. M. S. Schofield, A. Effler +215
The sensitivity of the Advanced LIGO detectors to gravitational waves can be affected by environmental disturbances external to the detectors themselves. Since the transition from…
Gravitational wave extraction and outer boundary conditions by perturbative matching
The Binary Black Hole Grand Challenge Alliance, :, A. M. Abrahams +42
We present a method for extracting gravitational radiation from a three-dimensional numerical relativity simulation and, using the extracted data, to provide outer boundary conditi…
Stable characteristic evolution of generic 3-dimensional single-black-hole spacetimes
The Binary Black Hole Grand Challenge Alliance, :, R. Gomez +42
We report new results which establish that the accurate 3-dimensional numerical simulation of generic single-black-hole spacetimes has been achieved by characteristic evolution wit…
Prospects for Fundamental Physics with LISA

In this paper, which is of programmatic rather than quantitative nature, we aim to further delineate and sharpen the future potential of the LISA mission in the area of fundamental…
Precession during merger 1: Strong polarization changes are observationally accessible features of strong-field gravity during binary black hole merger
R. O'Shaughnessy, L. London, J. Healy +1
The short gravitational wave signal from the merger of compact binaries encodes a surprising amount of information about the strong-field dynamics of merger into frequencies access…
