Models of black hole accretion disks are reviewed, with an emphasis on the theory of hard X-ray production. The following models are considered: i) standard, ii) super-critical, iii) two-temperature, and iv) disk+corona. New developments have recently been made in hydrodynamical models of accretion and in phenomenological radiative models fitting the observed X-ray spectra. Attempts to unify the two approaches are only partly successful.

  1. High-energy Emission from Turbulent Electron-ion Coronae of Accreting Black Holes

    astro-ph.HE 2026-01 conditional novelty 7.0 of 10

    Turbulent electron-ion coronae around accreting black holes self-regulate into a two-temperature state that generates nonthermal ions and X-ray spectra consistent with observations including an MeV tail.

  2. Accretion Regimes of Neutrino-Cooled Flows onto Black Holes

    astro-ph.HE 2025-07 conditional novelty 7.0 of 10

    A 1D relativistic disk model charts the accretion regimes of neutrino-cooled flows and predicts r-process outflows up to black hole masses of about 3000 solar masses.

  3. Very Massive, Rapidly Spinning Binary Black Hole Progenitors through Chemically Homogeneous Evolution -- The Case of GW231123

    astro-ph.HE 2025-08 conditional novelty 6.0 of 10

    Chemically homogeneous evolution of very massive, low-metallicity binaries can naturally produce the high masses and spins inferred for GW231123, with spins limited by the critical rotation rate.

  4. BASS LIII: The Eddington Ratio as the Primary Regulator of the Fraction of X-ray Emission in Active Galactic Nuclei

    astro-ph.GA 2025-07 conditional novelty 6.0 of 10

    In a hard-X-ray-selected sample of 236 nearby unobscured AGN, the 2-10 keV X-ray bolometric correction is primarily set by Eddington ratio, with the luminosity dependence vanishing below λEdd ≈ 0.01.
