The host halo masses of AGNs and quasars at z∼3−7 with TNG-Cluster, FLAMINGO and other cosmological galaxy simulations
Using large-scale cosmological simulations, this study reveals that while AGN luminosity generally increases with host halo mass up to a threshold, the relationship is highly non-linear with significant scatter, indicating that the most luminous quasars at z∼3−7 typically inhabit intermediate-mass haloes (1012−12.5 M⊙) rather than the most massive ones, a finding that aligns well with observational estimates.
