We present bhlight, a numerical scheme for solving the equations of general relativistic radiation magnetohydrodynamics (GRRMHD) using a direct Monte Carlo solution of the frequency-dependent radiative transport equation. bhlight is designed to evolve black hole accretion flows at intermediate accretion rate, in the regime between the classical radiatively efficient disk and the radiatively inefficient accretion flow (RIAF), in which global radiative effects play a sub-dominant but non-negligible role in disk dynamics. We describe the governing equations, numerical method, idiosyncrasies of our implementation, and a suite of test and convergence results. We also describe example applications to radiative Bondi accretion and to a slowly accreting Kerr black hole in axisymmetry.

  1. Identifying Observational Signatures of Flux Eruption Events in Supermassive Black Hole Accretion Flows with Machine Learning

    astro-ph.HE 2026-06 unverdicted novelty 6.0 of 10

    Machine learning on simulated images identifies that flux eruption events cause more diffuse, polarized, lower-flux millimeter emission with decreased Q-U loop rotation rate, achieving ~80% accuracy with random forest...

  2. Impact of neutrino-electron scattering and an improved treatment of pair processes on binary neutron star mergers

    astro-ph.HE 2026-06 unverdicted novelty 5.0 of 10

    Improved Monte Carlo neutrino transport in BNS merger simulations that includes inelastic electron scattering and refined pair processes produces lower heavy-lepton neutrino energies/luminosities and 50% higher ejecta mass.

  3. Neutrino pair annihilation driven jets from black-hole torus systems

    astro-ph.HE 2025-06 conditional novelty 5.0 of 10

    Neutrino pair annihilation in black hole-torus systems launches relativistic fireballs with isotropic energies up to about 10^51 erg and durations around 0.1 s, which can account for faint short GRBs and GRB precursors.
