Fig. 2: Photon and plasma spectra as a function of the external luminosity ℓext.
From: Radiative plasma simulations of black hole accretion flow coronae in the hard and soft states

a Escaping photon flux for simulations with ℓext = 0.1, 0.2, 0.4, 1, 3, 6, 10 (orange to turquoise curves). The values of ℓext are denoted with white dots in the colorbar. b Self-consistent plasma momentum distribution (in units of optical depth τT) for the same simulations. The spectra are provided as Source Data files.
