We investigate the correlation between the mass of a central supermassive black hole and the total gravitational mass of the host galaxy (M_tot). The results are based on 43 galaxy-scale strong gravitational lenses from the Sloan Lens ACS (SLACS) Survey whose black hole masses were estimated through two scaling relations: the relation between black hole mass and Sersic index (M_bh - n) and the relation between black hole mass and stellar velocity dispersion (M_bh - sigma). We use the enclosed mass within R_200, the radius within which the density profile of the early type galaxy exceeds the critical density of the Universe by a factor of 200, determined by gravitational lens models fitted to HST imaging data, as a tracer of the total gravitational mass. The best fit correlation, where M_bh is determined from M_bh - sigma relation, is log(M_bh) = (8.18 +/- 0.11) + (1.55 +/- 0.31) (log(M_tot) - 13.0) over 2 orders of magnitude in M_bh. From a variety of tests, we find that we cannot reliably infer a connection between M_bh and M_tot from the M_bh - n relation. The M_bh - M_tot relation provides some of the first, direct observational evidence to test the prediction that supermassive black hole properties are determined by the halo properties of the host galaxy.

  1. Darkness Visible: N-Body Simulations of Dark Matter Spikes in Hernquist Haloes

    astro-ph.CO 2024-11 reject novelty 6.0 of 10

    N-body simulations of adiabatic black hole growth in Hernquist haloes yield an empirical spike profile with outer halo depletion and a mass-ratio-dependent spike radius that deviates from analytical predictions.

  2. SIDM and CDM interpretations of the million-solar-mass lensing perturber JVAS B1938+666-$\mathcal{V}$

    astro-ph.GA 2026-06 unverdicted novelty 5.0 of 10

    SIDM core-collapse simulations produce a dense central core matching the lensing perturber, while CDM requires an IMBH with extreme tidal mass loss whose realism is left open.
