标题： Cosmological constraints on early dark energy from the full shape analysis of eBOSS DR16

摘要： 我们使用已完成的eBOSS巡天的数据评估了早期暗能量（EDE）解决哈勃张力的有效性，重点关注发光红星系（LRGs）、类星体（QSOs）和发射线星系（ELGs）。基于三种示踪物功率谱的全形状分析，我们进行了宇宙学参数测量。我们使用大规模结构的有效场论（EFTofLSS）来进行这种全形状分析。EDE以强烈的体积投影效应而闻名，这使得对宇宙学限制的解释具有挑战性。为了量化EDE全形状分析中的体积投影效应，我们通过广泛的模拟研究探索了不同先验选择对EFTofLSS系统参数的影响。我们将经典的高斯先验与已知可以缓解$\Lambda$CDM中体积投影效应的Jeffreys非信息先验进行了比较。我们的全形状分析结合了eBOSS和BOSS数据与Planck、外部重子声波振荡（BAO）、PantheonPlus和SH0ES超新星数据。与$\Lambda$CDM相比，EDE能够将张力从$5.2\sigma$减少到$3\sigma$。 在68%可信区间内，分别使用高斯先验和Jeffreys先验得出的导出值为：使用$f_\mathrm{EDE} = 0.1179_{-0.022}^{+0.025}$的$H_0=71.73_{-0.86}^{+0.82}$km/s/Mpc 和使用$f_\mathrm{EDE} = 0.1399_{-0.022}^{+0.023}$的$H_0=72.03_{-0.87}^{+0.82}$km/s/Mpc。 尽管与$\Lambda$冷暗物质模型相比，哈勃张力有所缓解，但加入eBOSS数据后，与Planck、外部BAO、PantheonPlus和SH0ES对BOSS数据完整形状分析的结果相比，EDE内部的张力从$2\sigma$增加到$3\sigma$。 这突显了在讨论旨在解决哈勃张力的模型时，纳入额外的大规模结构数据的重要性。 显示英文摘要

摘要： We evaluate the effectiveness of Early Dark Energy (EDE) in addressing the Hubble tension using data from the completed eBOSS survey, focusing on luminous red galaxies (LRGs), quasars (QSOs), and emission line galaxies (ELGs). We perform cosmological parameter measurements based on full shape analysis of the power spectrum of all three tracers. We conduct this full shape analysis with the effective field theory of large-scale structure (EFTofLSS). EDE is known to strongly suffer from volume projection effects, which makes the interpretation of cosmological constraints challenging. To quantify the volume projection effects within an EDE full shape analysis, we explore the impact of different prior choices on the nuisance parameters of EFTofLSS through an extensive mock study. We compare classical Gaussian priors to the non-informative Jeffreys prior, known to mitigate volume projection effects in $\Lambda$CDM. Our full shape analysis combines eBOSS and BOSS data with Planck, external Baryon Acoustic Oscillation (BAO), PantheonPlus, and SH0ES supernova data. EDE demonstrates to reduce the tension from $5.2\sigma$ to $3\sigma$ compared to $\Lambda$CDM. The derived values at a 68\% credible interval with Gaussian and Jeffreys priors are $H_0=71.73_{-0.86}^{+0.82}$ km/s/Mpc with $f_\mathrm{EDE} = 0.1179_{-0.022}^{+0.025}$ and $H_0=72.03_{-0.87}^{+0.82}$ km/s/Mpc with $f_\mathrm{EDE} = 0.1399_{-0.022}^{+0.023}$, respectively. Although the Hubble tension is mitigated compared to $\Lambda$CDM, the inclusion of eBOSS data amplifies the tension within EDE from $2\sigma$ to $3\sigma$, in contrast to the full shape analysis of BOSS data with Planck, external BAO, PantheonPlus, and SH0ES. This highlights the significance of incorporating additional large-scale structure data in discussions concerning models aiming to resolve the Hubble tension.
