We present a model independent analysis of the Pantheon+ supernova sample and study the dependence of the recovered values of H ₀, q ₀ and j ₀ on the redshift cut and on the modeling of peculiar velocities. In addition to the bulk velocity discussed previously, we also find a significant infall that we attribute to the presence of an overdensity out to a radius of R ≃ 120h ^-1Mpc.

我们提出了 Pantheon+ 超新星样品的模型独立分析，并研究了 H₀、q₀ 和 j₀ 的恢复值对红移切割和奇异速度建模的依赖性。除了前面讨论的体速之外，我们还发现了一个显着的下降，我们将其归因于半径为 R ≃ ^120h-1Mpc 的过密度的存在。
