Abstract

The Degree Angular Scale Interferometer (DASI) has measured the power spectrum of the cosmic microwave background anisotropy over the range of spherical harmonic multipoles 100 < l < 900. We compare these data, in combination with the COBE DMR results, to a seven-dimensional grid of adiabatic cold dark matter (CDM) models. Adopting the priors h > 0.45 and 0.0 ≤ τ c ≤ 0.4, we find that the total density of the universe Ω tot = 1.04 ± 0.06 and the spectral index of the initial scalar fluctuations n s = 1.01 in accordance with the predictions of inflationary theory. In addition, we find that the physical density of baryons Ω b h 2 = 0.022 , and the physical density of cold dark matter Ω cdm h 2 = 0.14 ± 0.04. This value of Ω b h 2 is consistent with that derived from measurements of the primeval deuterium abundance combined with big bang nucleosynthesis theory. Using the result of the Hubble Space Telescope ( HST ) Key Project, h = 0.72 ± 0.08, we find that Ω tot = 1.00 ± 0.04, the matter density Ω m = 0.40 ± 0.15, and the vacuum energy density Ω Λ = 0.60 ± 0.15. (All 68% confidence limits.)

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.
