Description
All GRMHD models employed by the Event Horizon Telescope to interpret horizon-scale emission from Sagittarius A and M87 develop magnetically driven polar outflows. These simulations are scale-free and can be rescaled to different black hole masses and accretion rates, making them an ideal framework to test the unification of accretion physics across mass scales. In this work, we investigate whether GRMHD models that best fit the two EHT sources are applicable to the broader population of radio-loud AGN. This requires that the resulting spectral energy distributions are consistent with those observed in AGN and that the models reproduce empirical correlations between black hole mass, radio, and X-ray emission, such as the fundamental plane of black hole accretion. In addition to matching the 230 GHz horizon-scale emission observed by the EHT, the models must also reproduce the large-scale radio jet emission. We find that most magnetically arrested disk (MAD) models fail to reproduce the typically flat radio spectra observed in AGN, whereas standard and normal evolution (SANE) models perform significantly better. Furthermore, we systematically investigate how different choices in GRMHD setup influence the resulting jet spectra.
