Constraints on Dark Matter Models from Supermassive Black Hole Evolution / Ellis, John ; Fairbairn, Malcolm ; Urrutia, Juan ; Vaskonen, Ville
A semi-analytical model for the evolution of galaxies and supermassive black holes (SMBHs) within the $Λ$CDM paradigm has been shown to yield stellar mass-BH mass relations that reproduce both the JWST and pre-JWST observations. [...]
