We investigate black hole-host galaxy scaling relations in cosmologicalsimulations with a self-consistent black hole growth and feedback model. Thesub-grid accretion model captures the key scalings governing angular momentumtransport from galactic scales down to parsec scales, while our kineticfeedback implementation enables the injection of outflows with propertieschosen to match observed nuclear outflows. We show that "quasar mode" feedbackcan have a large impact on the thermal properties of the intergalactic mediumand the growth of galaxies and massive black holes for kinetic feedbackefficiencies as low as 0.1% relative to the bolometric luminosity. Nonetheless,our simulations suggest that the black hole-host scaling relations are onlyweakly dependent on the effects of black hole feedback on galactic scales,owing to feedback suppressing the growth of galaxies and massive black holes bya similar amount. In contrast, the rate at which gravitational torques feed thecentral black hole relative to the host galaxy star formation rate governs theslope and normalization of the black hole-host correlations. Our resultssuggest that a common gas supply regulated by gravitational torques is theprimary driver of the observed co-evolution of black holes and galaxies.
