Fe Kα lines from accreting black holes are produced mostly outside 10 gravitational radii due to radial ionization gradients, allowing broad profiles without high spin.
The authors derive and calibrate analytical criteria, using a hydrogen-oxygen toy model and Cloudy simulations, that classify X-ray absorption states in photoionized gas across Thomson-thin and moderate-thick regimes, including scattering and boundary effects.
Requiring thermal stability and single-valuedness in the thin-disk Ṁ-Σ plane produces a viscosity law α(X) with X = P_gas/P_rad that eliminates the radiation-pressure dominated instability while preserving the effective-temperature profile.
New XRISM observations confirm a highly broadened, pulsating Fe K line from the accretion column of Hercules X-1 that varies with pulse phase and evolves with the 35-day precession cycle.
Black hole spin constraints for Cyg X-1 from XRISM Resolve data are strongly model-dependent, ranging from a*~0.99 with relxill to a*~0 with relxillCp or reflkerrD.
HST observations infer ~500 solar masses of inflowing low-metallicity gas in M81's central parsec that can sustain its advection-dominated accretion flow for 10^5 years.

Radiation-pressure instability is an artifact of constant-$\alpha$ closure
Requiring thermal stability and single-valuedness in the thin-disk Ṁ-Σ plane produces a viscosity law α(X) with X = P_gas/P_rad that eliminates the radiation-pressure dominated instability while preserving the effective-temperature profile.

XRISM/Resolve observations of Hercules X-1: a pulsating, highly broadened Fe K emission line from the neutron star accretion column
New XRISM observations confirm a highly broadened, pulsating Fe K line from the accretion column of Hercules X-1 that varies with pulse phase and evolves with the 35-day precession cycle.

Model dependence of XRISM black-hole spin constraints in Cyg X-1
Black hole spin constraints for Cyg X-1 from XRISM Resolve data are strongly model-dependent, ranging from a*~0.99 with relxill to a*~0 with relxillCp or reflkerrD.

Inflowing Gas in the Central Parsec of M81
HST observations infer ~500 solar masses of inflowing low-metallicity gas in M81's central parsec that can sustain its advection-dominated accretion flow for 10^5 years.
