Extended Data Fig. 6: Predicted 6.5–7.3 keV spectrum from simulation of the hot accretion flow.
From: An energetic hot wind from the low-luminosity active galactic nucleus M81*

The viewing angle is set to be 45∘ with respect to the jet axis. The blue, red and black curves show the blueshifted, redshifted and total spectrum, respectively. The spectra have been convolved with the HEG instrumental response. The black crosses mark the observed spectrum as a reference. The error bars are of 1σ. The observed Fe XXVI and XXV lines have an equivalent width substantially higher than predicted by the hot accretion flow.
