AGN with black-hole masses above 10^8.5 solar masses may occupy halos ~0.4 dex more massive than matched control galaxies, though the difference remains consistent with uncertainties.
X-ray AGN at intermediate redshifts live in dark matter halos of mass ~10^13 solar masses with no significant dependence on black hole mass, Eddington ratio or X-ray luminosity.
Calculations show current pulsar timing arrays have poor prospects for detecting gravitational wave memory, but LISA is likely to see 1-10 events with SNR exceeding 5 in its 4-year mission.
