TestingΛCDMwith the growth functionδ(a): Current constraints
Open accessAbstract
We have compiled a data set consisting of 22 data points at a redshift range (0.15, 3.8) which can be used to constrain the linear perturbation growth rate $f=\frac{d\mathrm{ln}\ensuremath{\delta}}{d\mathrm{ln}a}$. Five of these data points constrain directly the growth rate $f$ through either redshift distortions or change of the power spectrum with redshift. The rest of the data points constrain $f$ indirectly through the rms mass fluctuation ${\ensuremath{\sigma}}_{8}(z)$ inferred from ${L}_{y}\mathrm{\text{\ensuremath{-}}}\ensuremath{\alpha}$ at various redshifts. Our analysis tests the consistency of the $\ensuremath{\Lambda}\mathrm{CDM}$ model and leads to a constraint of the Wang-Steinhardt growth index $\ensuremath{\gamma}$ [defined from $f={\ensuremath{\Omega}}_{m}(a{)}^{\ensuremath{\gamma}}$] as $\ensuremath{\gamma}={0.67}_{\ensuremath{-}0.17}^{+0.20}$. This result is clearly consistent at $1\ensuremath{\sigma}$ with the value $\ensuremath{\gamma}=\frac{6}{11}=0.545$ predicted by $\ensuremath{\Lambda}\mathrm{CDM}$. We also apply our analysis on a new null test of $\ensuremath{\Lambda}\mathrm{CDM}$ which is similar to the one recently proposed by Chiba and Nakamura (arXiv:0708.3877) but does not involve derivatives of the expansion rate $H(z)$. This also leads to the fact that $\ensuremath{\Lambda}\mathrm{CDM}$ provides an excellent fit to the current linear growth data.

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.
