Effects of anisotropy in an anisotropic extension of wCDM model
arxiv(2024)
摘要
In this paper, we derive observational constraints on an anisotropic wCDM
model from observational data including Baryonic Acoustic Oscillations (BAOs),
Cosmic Chronometer (CC), Big Bang Nucleosynthesis (BBN), Pantheon Plus (PP)
compilation of Type Ia supernovae, and SH0ES Cepheid host distance anchors. We
find that anisotropy is of the order 10^-13, and its presence in the wCDM
model reduces H_0 tension by ∼ 2σ and ∼ 1σ in the
analyses with BAO+CC+BBN+PP and BAO+CC+BBN+PPSH0ES data combinations,
respectively. In both analyses, the quintessence form of dark energy is favored
at 95% CL.
