Evolution of the AGN power (top panel) as a function of time for our highest-resolution hydrodynamic (dark blue) and MHD (light blue) runs. The bottom panel presents the evolution of the total cold gas mass formed (solid line), as well as its associated specific angular momentum (dashed line). The average AGN power is broadly constant from one set-up to an other, but shows weaker fluctuations in MHD set-up. While similar quantities of cold gas are formed in each run, its overall specific angular momentum is found to be larger in the hydrodynamic case due to the formation of a massive disc, consistent with previous work (Li & Bryan 2014a; Qiu et al. 2019; Ehlert et al. 2023).
