论文摘要
使用有效的大规模结构(EFTBOSS)的单循环预测对BOSS DR12功率谱的完整形状进行分析,导致对$λ$ CDM模型的扩展有了新的限制,例如早期的Dark Energy(EDE),该模型已被建议作为“ Hubble张力”的分辨率。在本文中,根据对Boss窗口函数的归一化校正,我们重新评估Eftboss在EDE上的约束功率。总体而言,我们发现EDE上的Eftboss的约束被削弱了,与普朗克和常规的BAO/$Fσ_8$测量相比,它的变化很小。 Planck数据与Eftboss的组合提供了EDE $ f _ {\ rm eDe} <0.083 $ 95%C.L.的最大分数贡献的限制。 (相比之下,不正确的标准化为$ <0.054 $,而没有全面数据的$ <0.088 $),哈勃张力降低到$2.1σ$。但是,EFTBOSS数据不利于Atacama Cosmology望远镜的分析所偏爱的更极端模型。我们还表明,更新的万神殿+类型IA超新星分析可以稍微增加EDE的限制。然而,通过SH0E将SN1A量化的量化加入将EDE的偏好增加到$5σ$,产生了$ f _ {\ rm eDe} \ sim 0.12^{+0.03} _ { - 0.02} _ { - 0.02} $ abour Redshift $ z__c = 4365^$} $我们的结果表明,EFTBOSS数据(单独或与Planck数据相结合)并不排除哈勃张力的EDE分辨率。
Analyses of the full shape of BOSS DR12 power spectrum using the one-loop prediction from the Effective Field Theory of Large-Scale Structure (EFTBOSS) have led to new constraints on extensions to the $Λ$CDM model, such as Early Dark Energy (EDE) which has been suggested as a resolution to the "Hubble tension". In this paper, we re-assess the constraining power of the EFTBOSS on EDE in light of a correction to the normalization of BOSS window functions. Overall we find that constraints from EFTBOSS on EDE are weakened, and represent a small change compared to constraints from Planck and the conventional BAO/$fσ_8$ measurements. The combination of Planck data with EFTBOSS provides a bound on the maximal fractional contribution of EDE $f_{\rm EDE}<0.083$ at 95% C.L. (compared to $<0.054$ with the incorrect normalization, and $<0.088$ without full-shape data) and the Hubble tension is reduced to $2.1σ$. However, the more extreme model favored by an analysis with just data from the Atacama Cosmology Telescope is disfavored by the EFTBOSS data. We also show that the updated Pantheon+ Type Ia supernova analysis can slightly increase the constraints on EDE. Yet, the inclusion of the SN1a magnitude calibration by SH0ES strongly increases the preference for EDE to above $5σ$, yielding $f_{\rm EDE}\sim 0.12^{+0.03}_{-0.02}$ around the redshift $z_c=4365^{+3000}_{-1100}$. Our results demonstrate that EFTBOSS data (alone or combined with Planck data) do not exclude the EDE resolution of the Hubble tension.
