A new Bayesian analysis of VLBI observations of GW170817's jet afterglow constrains the viewing angle to 16.8-19.2 degrees and measures H0 = 65.5 ± 4.4 km s^{-1} Mpc^{-1}, closer to Planck than SH0ES values.

GPU-accelerated nested sampling on GW170817 demonstrates that switching to a uniform-in-dL prior shifts the H0 tail and median far more than post-hoc reweighting captures, due to an under-sampled (dL, iota) bimodality.
Relativistic MHD simulations of jet-driven shocks in post-merger ejecta show the GW-EM delay depends weakly on viewing angle and opacity, with a choked-jet model best matching GRB 170817A luminosity, delay, and duration.
Simulations of VLBI networks including SKA-Mid in AA* and AA4 configurations predict 2x better size constraints, 4-30x improved Declination localization, and 3x better off-axis proper-motion detection for GRBs, extending measurable events to z approximately 0.25.
Simulations of the BSD instrument for POLAR-2 show it can localize faint GRBs like GRB 170817A to about 1.5 degrees accuracy, meeting requirements for supporting GRB polarimetry.
Latest GW neutron star merger rates are consistent with short GRBs being produced by BNS mergers if jets are wide or rates low, with NSBH mergers subdominant.
Identifies eight Fermi-GBM sGRBs similar to 170817A via hardness-ratio K-means clustering and estimates ~5 GW+sGRB events by end of O4.
BILBY is validated on simulated compact binary signals and reproduces the eleven GWTC-1 results with configuration and output files provided for reproduction.

Rapid Hubble constant inference from GW170817 using GPU-accelerated nested sampling: prior sensitivity and the limits of post-hoc reweighting
GPU-accelerated nested sampling on GW170817 demonstrates that switching to a uniform-in-dL prior shifts the H0 tail and median far more than post-hoc reweighting captures, due to an under-sampled (dL, iota) bimodality.

Modelling the delayed shock-breakout emission following jet-launching binary neutron star mergers via relativistic MHD simulations
Relativistic MHD simulations of jet-driven shocks in post-merger ejecta show the GW-EM delay depends weakly on viewing angle and opacity, with a choked-jet model best matching GRB 170817A luminosity, delay, and duration.

Wide Jets or Low Rates: Reconciling Short GRB and Gravitational-Wave Neutron Star Merger Rates
