Gravitational-wave detections are enabling measurements of the rate of coalescences of binaries composed of two compact objects -- neutron stars and/or black holes. The coalescence rate of binaries containing neutron stars is further constrained by electromagnetic observations, including Galactic radio binary pulsars and short gamma-ray bursts. Meanwhile, increasingly sophisticated models of compact objects merging through a variety of evolutionary channels produce a range of theoretically predicted rates. Rapid improvements in instrument sensitivity, along with plans for new and improved surveys, make this an opportune time to summarise the existing observational and theoretical knowledge of compact-binary coalescence rates.

  1. A Four-dimensional Model-agnostic Probe into the Astrophysical Origins of Binary Black Hole Subpopulations

    astro-ph.HE 2026-07 conditional novelty 7.0 of 10

    A GPU-accelerated binned Gaussian process yields the first model-agnostic 4D BBH population in (m1, q, χeff, χp), revealing four mass-based subpopulations and new spin-mass-ratio correlations.

  2. Stable mass transfer in massive binaries leading to merging black holes

    astro-ph.SR 2025-12 conditional novelty 7.0 of 10

    Stable mass transfer in massive binaries, modeled with the accreting star's altered structure, produces merging black holes matching LIGO/Virgo masses and spins.

  3. When (not) to trust Monte Carlo approximations for hierarchical Bayesian inference

    astro-ph.HE 2025-09 conditional novelty 7.0 of 10

    A unified error statistic E-hat measures information lost to Monte Carlo noise in hierarchical Bayesian inference, with a recommended cutoff of 0.2 bits.

  4. Gravitational Wave Modeling of White-Dwarf--Compact-Object Binaries and Observational Outlook

    astro-ph.HE 2026-07 conditional novelty 6.0 of 10

    WD–CO binaries produce unique GW waveforms with a sharp f_max cutoff; LGWA/DECIGO will detect many end stages, while terrestrial detectors will not mistake them for sub-solar compact objects.

  5. Uncovering Hierarchical Sub-Population of Binary Black Holes

    astro-ph.HE 2026-07 conditional novelty 6.0 of 10

    A flexible six-component fit to 259 LIGO/Virgo/KAGRA black-hole mergers finds a roughly geometric sequence of mass peaks but no aligned-spin signal except in the lowest-mass component.

  6. Formation of rotating supergiants via stellar mergers in dense clusters: Implications for black hole natal spins

    astro-ph.HE 2026-07 conditional novelty 6.0 of 10

    Stellar mergers with mass ratio q≳0.3 in young clusters can produce blue-supergiant progenitors that leave black holes with dimensionless spins a≃0.5–0.8, reducing post-merger retention and hierarchical-merger rates.

  7. nmma: An extended Bayesian framework for Nuclear Multimessenger Astronomy in the Era of Next-Generation Detectors

    astro-ph.IM 2026-07 accept novelty 6.0 of 10

    nmma now jointly samples nuclear EoS parameters with GW and EM data via TOV emulators and Fiesta surrogates, delivering 20–60× speedups and future H0–nuclear constraints.

  8. The Very Late Time Afterglow of GW170817 Favors a Wobbling Jet

    astro-ph.HE 2026-05 unverdicted novelty 6.0 of 10

    A ring-shaped wobbling jet explains the shallow late-time afterglow decay of GW170817 better than a collimated jet at 4.8 sigma significance, implying a ~27 degree wobble angle.

  9. Measurement prospects for the pair-instability mass cutoff with gravitational waves

    astro-ph.HE 2026-02 conditional novelty 6.0 of 10

    Simulations show a 40-50 solar-mass black-hole cutoff is not guaranteed to be confidently recovered from GWTC-4-like catalogs, spurious detections are unlikely, and O4 data would reduce cutoff-mass uncertainty by at l...

  10. Signatures of a subpopulation of hierarchical mergers in the GWTC-4 gravitational-wave dataset

    gr-qc 2026-01 conditional novelty 6.0 of 10

    Using a joint effective-spin and precession-spin model on 155 gravitational-wave events, the authors infer that the hierarchical (second-generation) merger fraction rises sharply above ~46 M_sun and peaks again near 1...

  11. Signatures of a subpopulation of hierarchical mergers in the GWTC-4 gravitational-wave dataset

    gr-qc 2026-01 unverdicted novelty 6.0 of 10

    GWTC-4 data show a transition to nearly all hierarchical mergers above 46 solar masses, with the hierarchical rate peaking at 15.7 solar masses, indicating mass-dependent substructure in black hole spins.
