How accurate is Spectral Einstein Code (SpEC)? And what limits its accuracy?
Himanshu Chaudhary, Mark A. Scheel, Robert Owen +4
The improved sensitivity of upcoming gravitational-wave detectors will require correspondingly more accurate binary black hole (BBH) simulations. Given the high cost of such simula…
Finding black hole spins efficiently during a numerical binary evolution
Himanshu Chaudhary, Rob Owen, Mark A. Scheel +1
The dynamics of a binary black hole system depend on its masses and spins. For a binary at finite separation, it is not possible to define these quantities in an unambiguous way; h…
Parameter control for binary black hole initial data
Iago B. Mendes, Nils L. Vu, Oliver Long +2
When numerically solving Einstein's equations for binary black holes (BBH), we must find initial data on a three-dimensional spatial slice by solving constraint equations. The cons…
The SXS Collaboration's third catalog of binary black hole simulations
Mark A. Scheel, Michael Boyle, Keefe Mitman +56
We present a major update to the Simulating eXtreme Spacetimes (SXS) Collaboration's catalog of binary black hole simulations. Using highly efficient spectral methods implemented i…
Imprints of Changing Mass and Spin on Black Hole Ringdown
Hengrui Zhu, Frans Pretorius, Sizheng Ma +8
We numerically investigate the imprints of gravitational radiation-reaction driven changes to a black hole's mass and spin on the corresponding ringdown waveform. We do so by compa…
Nonlinear Effects In Black Hole Ringdown From Scattering Experiments I: spin and initial data dependence of quadratic mode coupling
Hengrui Zhu, Justin L. Ripley, Frans Pretorius +13
We investigate quadratic quasinormal mode coupling in black hole spacetime through numerical simulations of single perturbed black holes using both numerical relativity and second-…
