Running Hubble Tension and a H0 Diagnostic

论文摘要
哈勃张力通常是在本地确定的哈勃常数$ h_0 $之间的不匹配与从flat $λ$ CDM宇宙学推断的值之间的不匹配。从本质上讲，张力归结为两个数字之间的分歧。在这里，假设张力是宇宙学的，我们预测在$λ$ CDM中，应该有其他推断的$ H_0 $的值，并且可以预期“ $ H_0 $的运行”。 $ H_0 $的这些额外确定可以追溯到弗里德曼·莱玛·罗伯森 - 罗伯逊 - 沃克（FLRW）宇宙宇宙学框架和当前标准模型中宇宙的有效状态方程（EOS）之间的差异。我们介绍了一个诊断，该诊断限制为$ h_0 $。
Hubble tension is routinely presented as a mismatch between the Hubble constant $H_0$ determined locally and a value inferred from the flat $Λ$CDM cosmology. In essence, the tension boils down to a disagreement between two numbers. Here, assuming the tension is cosmological in origin, we predict that within flat $Λ$CDM there should be other inferred values of $H_0$, and that a "running of $H_0$ with redshift" can be expected. These additional determinations of $H_0$ may be traced to a difference between the effective equation of state (EoS) of the Universe within the Friedmann-Lemaître-Robertson-Walker (FLRW) cosmology framework and the current standard model. We introduce a diagnostic that flags such a running of $H_0$.
