High-redshift quasars in the Cold Dark Matter cosmogony
Abstract
We argue that the observed space density of luminous quasars between z = 2 and z = 4 is compatible with the cold dark matter (CDM) model if quasars are short lived and radiate at about the Eddington limit. However, according to the CDM model the abundance of high luminosity quasars must decline exponentially at higher redshifts. Even if all proto-galaxies form quasars, and about 1% of the baryons within a protogalaxy collapse into a compact object, we would expect a steep fall in the density of quasars with L > 1047ergs−1 at redshifts z ≳ 5. The existence of a cut-off in the quasar numbers at high redshift could therefore supply an important test of the CDM theory.

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.
