Supernova Limits on the Cosmic Equation of State
Open accessAbstract
We use Type Ia supernovae studied by the High- z Supernova Search Team to constrain the properties of an energy component that may have contributed to accelerating the cosmic expansion. We find that for a flat geometry the equation-of-state parameter for the unknown component, α x = P x /ρ x , must be less than -0.55 (95% confidence) for any value of Ω m , and it is further limited to α x < -0.60 (95% confidence) if Ω m is assumed to be greater than 0.1. These values are inconsistent with the unknown component being topological defects such as domain walls, strings, or textures. The supernova (SN) data are consistent with a cosmological constant (α x = -1) or a scalar field that has had, on average, an equation-of-state parameter similar to the cosmological constant value of -1 over the redshift range of z ≈ 1 to the present. SN and cosmic microwave background observations give complementary constraints on the densities of matter and the unknown component. If only matter and vacuum energy are considered, then the current combined data sets provide direct evidence for a spatially flat universe with Ω tot = Ω m + Ω Λ = 0.94 ± 0.26 (1 σ).

“An alternative approach with good precedent (Garnavich et al. 1998; Perlmutter et al. 1999) is to consider a flat universe and a generalized dark energy component parameterized by its (assumed) constant equation of state w ¼ P= c2.”

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.
