Comparison of the thermal solutions for the MAD numerical simulation at r = 8 rg in an AGN with MBH = 108M (solid lines) and in an XRB with MBH = 10 M (dashed lines). The gray and gold lines show the hot and cold branches, respectively. The hysteresis cycle for AGN extends over a much wider range of , so that low-luminosity AGN with as low as 10−7 are expected to be found in a disk-like spectral state.
