We present a coordinate-independent method for extracting mass (M) and angular momentum (J) of a black hole in numerical simulations. This method, based on the isolated horizon framework, is applicable both at late times when the black hole has reached equilibrium, and at early times when the black holes are widely separated. We show how J and M can be determined in numerical simulations in terms of only those quantities which are intrinsic to the apparent horizon. We also present a numerical method for finding the rotational symmetry vector field (required to calculate J) on the horizon.

  1. Shaping black hole resonances I. Black hole ringdown as a spectral filtering process

    gr-qc 2026-05 unverdicted novelty 7.0 of 10

    Quasinormal mode excitation in black hole ringdown equals the Fourier transform of the perturbation evaluated at the mode frequency, so black holes act as resonant spectral filters.

  2. Conformal-Mapping Method for Horizon Multipoles in Numerical Relativity: Implementation, Kerr Validation, and Applications Beyond Axisymmetry

    gr-qc 2026-08 conditional novelty 6.0 of 10

    A first numerical implementation of the symmetry-free conformal horizon multipole construction, validated on Kerr and applied to an equal-mass non-spinning binary merger.

  3. Ringdown and lensing of triple systems

    gr-qc 2026-05 unverdicted novelty 6.0 of 10

    Numerical relativity simulations of triple black hole systems reveal redshift effects and gravitational lensing in ringdown signals from head-on mergers, with no additional black hole formation from amplified waves.

  4. Cusp Formation in Merging Black Hole Horizons

    gr-qc 2026-05 unverdicted novelty 6.0 of 10

    Numerical study of cusp formation on horizons in head-on non-spinning black hole mergers, with analysis of mass and multipole behavior at the cusp and a proposed phenomenological model.

  5. AthenaK simulations of the binary black hole merger GW150914

    gr-qc 2025-06 conditional novelty 5.0 of 10

    A new open-source GPU code, AthenaK, reproduces the GW150914 merger: remnant mass within 0.01%, spin within 0.02%, and waveform phase within about 0.35 radians of established simulations.

  6. Strong Field Scattering of Black Holes: Assessing Resummation Strategies

    gr-qc 2024-11 conditional novelty 5.0 of 10

    High-energy equal-mass black hole scattering data show that L-resummation, weob, and SEOB-PM models all develop pathological behavior, with NR-calibrated pseudo-5PM corrections and Padé-resummed EOB potentials offerin...

  7. The Fifth RIT Catalog of Binary Black Hole Simulations: Multiple-Resolution Studies of Eccentric Orbits

    gr-qc 2026-06 unverdicted novelty 3.0 of 10

    Fifth RIT catalog adds 248 new binary black hole waveforms emphasizing eccentric orbits with convergence studies on 10 simulations, reaching 2129 total cases.
