Gauge Boundary conditions to mitigate center-of-mass drift in BBH simulations
Dongze Sun, Sizheng Ma, Mark A. Scheel +1
Long-term numerical relativity (NR) simulations of binary black hole (BBH) systems in the Spectral Einstein Code (SpEC) code exhibit an unexpected exponential drift of the center-o…
GW250114 reveals black hole horizon signatures
Neil Lu, Sizheng Ma, Ornella J. Piccinni +2
The horizon of a black hole, the "surface of no return", is characterized by its rotation frequency and surface gravity . A striking signature is that any infalling object…
Probing Direct Waves in Black Hole Ringdowns
Naritaka Oshita, Sizheng Ma, Yanbei Chen +1
Merger gravitational waves from binary black hole coalescence carry rich information about the underlying spacetime dynamics. We analyze merger waves from comparable-mass and extre…
Emergent Turbulence in Nonlinear Gravity
Sizheng Ma, Luis Lehner, Huan Yang +3
Gravity in nonlinear and dynamical regimes underpins spectacular astrophysical phenomena and observable consequences, from the early universe to black hole collisions. In these ext…
Impact of Detector Calibration Accuracy on Black Hole Spectroscopy
Mallika R. Sinha, Ling Sun, Sizheng Ma
Systematic errors in detector calibration can bias signal analyses and potentially lead to incorrect interpretations suggesting violations of general relativity. In this study, we…
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…
Black hole spectroscopy: from theory to experiment
Emanuele Berti, Vitor Cardoso, Gregorio Carullo +65
The "ringdown" radiation emitted by oscillating black holes has great scientific potential. By carefully predicting the frequencies and amplitudes of black hole quasinormal modes a…
Statistical identification of ringdown modes with rational filters
Neil Lu, Sizheng Ma, Ornella J. Piccinni +2
Measuring quasinormal modes (QNMs) during the ringdown phase of binary black hole coalescences provides key insights into merger dynamics and enables tests of the no-hair theorem.…
Signatures of Quantum Gravity in Gravitational Wave Memory
Nils Deppe, Lavinia Heisenberg, Lawrence E. Kidder +6
We study the impact of quantum corrections to gravitational waveforms on the gravitational wave memory effect. In certain quantum gravity theories and semi-classical frameworks, bl…
