BLACK HOLE GROWTH AND ACTIVE GALACTIC NUCLEI OBSCURATION BY INSTABILITY-DRIVEN INFLOWS IN HIGH-REDSHIFT DISK GALAXIES FED BY COLD STREAMS
Open accessAbstract
Disk galaxies at high redshift have been predicted to maintain high gas surface densities due to continuous feeding by intense cold streams leading to violent gravitational instability, transient features, and giant clumps. Gravitational torques between the perturbations drive angular momentum out and mass in, and the inflow provides the energy for keeping strong turbulence. We use analytic estimates of the inflow for a self-regulated unstable disk at a Toomre stability parameter Q ∼ 1, and isolated galaxy simulations capable of resolving the nuclear inflow down to the central parsec. We predict an average inflow rate ∼10 M ☉ yr −1 through the disk of a 10 11 M ☉ galaxy, with conditions representative of z ∼ 2 stream-fed disks. The inflow rate scales with disk mass and (1 + z ) 3/2 . It includes clump migration and inflow of the smoother component, valid even if clumps disrupt. This inflow grows the bulge, while only a fraction of ≳ 10 −3 of it needs to accrete onto a central black hole (BH), in order to obey the observed BH–bulge relation. A galaxy of 10 11 M ☉ at z ∼ 2 is expected to host a BH of ∼10 8 M ☉ , accreting on average with moderate sub-Eddington luminosity L X ∼ 10 42 –10 43 erg s −1 , accompanied by brighter episodes when dense clumps coalesce. We note that in rare massive galaxies at z ∼ 6, the same process may feed ∼10 9 M ☉ BH at the Eddington rate. High central gas column densities can severely obscure active galactic nuclei in high-redshift disks, possibly hindering their detection in deep X-ray surveys.

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.
