Abstract

We have measured the counts-in-cells fluctuations of 268 Lyman-break galaxies with spectroscopic redshifts in six 9' × 9' fields at z ~ 3. The variance of galaxy counts in cubes of comoving side length 7.7, 11.9, 11.4 h 100 −1 Mpc is σ gal 2 ~1.3±0.4 for Ω M = 1, 0.2 open, 0.3 flat, implying on these scales a bias of σ gal /σ mass = 6.0 ± 1.1, 1.9 ± 0.4, and 4.0 ± 0.7. The bias and abundance of Lyman-break galaxies are surprisingly consistent with a simple model of structure formation that assumes only that galaxies form within dark matter halos, that Lyman-break galaxies' rest-UV luminosities are tightly correlated with their dark masses, and that matter fluctuations are Gaussian and have a linear power-spectrum shape at z ~ 3 similar to that determined locally (Γ ~ 0.2). This conclusion is largely independent of cosmology or spectral normalization σ 8 . A measurement of the masses of Lyman-break galaxies would in principle distinguish between different cosmological scenarios.

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.
