The increasing tension between the different local direct measurements of the Hubble expansion rate and that inferred from the cosmic microwave background observation by the $\mathrm{\Lambda }$-cold-dark-matter model could be a smoking gun of new physics, if not caused by either observational systematics or local bias. We generalize previous investigation on the local bias from a local void by globally fitting the Pantheon sample over all parameters in the radial profile function of a local void described by an inhomogeneous but isotropic Lemaître-Tolman-Bondi metric with a cosmological constant. Our conclusion strengthens the previous studies that the current tension on Hubble constant cannot be saved by a local void alone.

观测数据是否有利于局部空洞？

哈勃膨胀率的不同局部直接测量结果与宇宙微波背景观测推断的结果之间的张力增加 $\mathrm{\Lambda }$如果不是由观测系统学或局部偏差引起的，冷暗物质模型可能是新物理学的吸烟枪。我们通过在局部空隙的径向剖面函数的所有参数上全局拟合万神殿样本，概括先前对局部空隙的局部偏差的研究，该局部空隙由具有宇宙常数的非均匀但各向同性的 Lemaître-Tolman-Bondi 度量描述。我们的结论加强了先前的研究，即哈勃常数当前的张力不能仅靠局部空洞来挽救。
