Mass-ratio and Magnetic Flux-Dependence of Modulated Accretion from Circumbinary Disks
Scott C. Noble, Julian H. Krolik, Manuela Campanelli +4
Accreting supermassive binary black holes (SMBBHs) are potential multi-messenger sources because they emit both gravitational wave and electromagnetic (EM) radiation. Past work has…
Deploying a Top-100 Supercomputer for Large Parallel Workloads: the Niagara Supercomputer
Marcelo Ponce, Ramses van Zon, Scott Northrup +14
Niagara is currently the fastest supercomputer accessible to academics in Canada. It was deployed at the beginning of 2018 and has been serving the research community ever since. T…
Initial-data contribution to the error budget of gravitational waves from neutron-star binaries
Antonios Tsokaros, Bruno C. Mundim, Filippo Galeazzi +2
As numerical calculations of inspiralling neutron-star binaries reach values of accuracy that are comparable with those of binary black holes, a fine budgeting of the various sourc…
Inspiralling, Non-Precessing, Spinning Black Hole Binary Spacetime via Asymptotic Matching
Brennan Ireland, Bruno C. Mundim, Hiroyuki Nakano +1
We construct a new global, fully analytic, approximate spacetime which accurately describes the dynamics of non-precessing, spinning black hole binaries during the inspiral phase o…
Inspiraling black-hole binary spacetimes: Challenges in transitioning from analytical to numerical techniques
Yosef Zlochower, Hiroyuki Nakano, Bruno C. Mundim +3
We explore how a recently developed analytical black-hole binary spacetime can be extended using numerical simulations to go beyond the slow-inspiral phase. The analytic spacetime…
Approximate black hole binary spacetime via asymptotic matching
Bruno C. Mundim, Hiroyuki Nakano, Nicolás Yunes +3
We construct a fully analytic, general relativistic, nonspinning black hole binary spacetime that approximately solves the vacuum Einstein equations everywhere in space and time fo…
Error-analysis and comparison to analytical models of numerical waveforms produced by the NRAR Collaboration
Ian Hinder, Alessandra Buonanno, Michael Boyle +53
The Numerical-Relativity-Analytical-Relativity (NRAR) collaboration is a joint effort between members of the numerical relativity, analytical relativity and gravitational-wave data…
GRHydro: A new open source general-relativistic magnetohydrodynamics code for the Einstein Toolkit
Philipp Moesta, Bruno C. Mundim, Joshua A. Faber +7
We present the new general-relativistic magnetohydrodynamics (GRMHD) capabilities of the Einstein Toolkit, an open-source community-driven numerical relativity and computational re…
Circumbinary MHD Accretion into Inspiraling Binary Black Holes
Scott C. Noble, Bruno C. Mundim, Hiroyuki Nakano +4
As 2 black holes bound to each other in a close binary approach merger their inspiral time becomes shorter than the characteristic inflow time of surrounding orbiting matter. Using…
Study of Conformally Flat Initial Data for Highly Spinning Black Holes and their Early Evolutions
Carlos O. Lousto, Hiroyuki Nakano, Yosef Zlochower +2
We study conformally-flat initial data for an arbitrary number of spinning black holes with exact analytic solutions to the momentum constraints constructed from a linear combinati…
The NINJA-2 catalog of hybrid post-Newtonian/numerical-relativity waveforms for non-precessing black-hole binaries
P. Ajith, Michael Boyle, Duncan A. Brown +45
The Numerical INJection Analysis (NINJA) project is a collaborative effort between members of the numerical relativity and gravitational wave data analysis communities. The purpose…
The Einstein Toolkit: A Community Computational Infrastructure for Relativistic Astrophysics
Frank Löffler, Joshua Faber, Eloisa Bentivegna +10
We describe the Einstein Toolkit, a community-driven, freely accessible computational infrastructure intended for use in numerical relativity, relativistic astrophysics, and other…
Hybrid black-hole binary initial data
Bruno C. Mundim, Bernard J. Kelly, Yosef Zlochower +2
Traditional black-hole binary puncture initial data is conformally flat. This unphysical assumption is coupled with a lack of radiation signature from the binary's past life. As a…
A Numerical Study of Boson Star Binaries
Bruno C. Mundim
This thesis describes a numerical study of binary boson stars within the context of an approximation to general relativity. The approximation we adopt places certain restrictions o…
Advances in Simulations of Generic Black-Hole Binaries
Manuela Campanelli, Carlos O. Lousto, Bruno C. Mundim +3
We review some of the recent dramatic developments in the fully nonlinear simulation of generic, highly-precessing, black-hole binaries, and introduce a new approach for generating…
