Abstract

We use a comprehensive database of black hole masses ( M BH ) and nuclear luminosities to investigate the relationship between radio emission and M BH . Our sample covers a wide range of nuclear activity, from nearby inactive nuclei to classical Seyfert 1 nuclei and luminous quasars. Contrary to some previous studies, we find that the radio continuum power, either integrated for the entire galaxy or isolated for the core, correlates poorly with M BH . The degree of nuclear radio loudness, parameterized by the radio-to-optical luminosity ratio R , also shows no clear dependence on M BH . Radio-loud nuclei exist in galaxies with a wide range of M BH , from ~10 6 to a few times 10 9 M ☉ , and in a variety of hosts, from disk-dominated spiral to giant elliptical galaxies. We demonstrate that R is strongly inversely correlated with L / L E , the ratio of nuclear luminosity to the Eddington luminosity, and hence with the mass accretion rate. Most or all of the weakly active nuclei in nearby galaxies are radio-loud, highly sub-Eddington systems that are plausibly experiencing advection-dominated accretion.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
