Lyman-α constraints on warm and on warm-plus-cold dark matter models
Open accessAbstract
We revisit Lyman-α bounds on the dark matter mass in Λ Warm Dark Matter (ΛWDM) models, and derive new bounds in the case of mixed Cold plus Warm models (ΛCWDM), using a set up which is a good approximation for several theoretically well-motivated dark matter models. We combine WMAP5 results with two different Lyman-α data sets, including observations from the Sloan Digital Sky Survey. We pay a special attention to systematics, test various possible sources of error, and compare the results of different statistical approaches. Expressed in terms of the mass of a non-resonantly produced sterile neutrino, our bounds read m NRP ⩾ 8 keV (frequentist 99.7% confidence limit) or m NRP ⩾ 12.1 keV (Bayesian 95% credible interval) in the pure ΛWDM limit. For the mixed model, we obtain limits on the mass as a function of the warm dark matter fraction F WDM . Within the mass range studied here (5 keV < m NRP < ∞ ), we find that any mass value is allowed when F WDM < 0.6 (frequentist 99.7% confidence limit); similarly, the Bayesian joint probability on ( F WDM , 1/ m NRP ) allows any value of the mass at the 95% confidence level, provided that F WDM < 0.35.

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.
