Formation of the First Supermassive Black Holes

Open access
Bromm, Volker, Loeb, Abraham·2003·The Astrophysical Journal

Abstract

We consider the physical conditions under which supermassive black holes could have formed inside the first galaxies. Our smoothed particle hydrodynamics simulations indicate that metal-free galaxies with a virial temperature of ~10 4 K and suppressed H 2 formation (due to an intergalactic UV background) tend to form a binary black hole system that contains a substantial fraction (≳10%) of the total baryonic mass of the host galaxy. Fragmentation into stars is suppressed without substantial H 2 cooling. Our simulations follow the condensation of ~5 × 10 6 M ☉ around the two centers of the binary down to a scale of ≲0.1 pc. Low-spin galaxies form a single black hole instead. These early black holes lead to quasar activity before the epoch of reionization. Primordial black hole binaries lead to gravitational radiation emission at redshifts z ≳ 10 that would be detectable by Laser Interferometer Space Antenna .

    “…star formation is therefore expected to occur, and the subsequent negative feedback due to supernova explosions would prevent the assembly of large quantities of gas in the center of the shallow dark matter (DM) potential well that characterizes the first dwarf galaxies (e.g., Dekel & Silk 1986).”

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.
