论文摘要
宇宙学的标准模型是$λ$ CDM模型，描述了宇宙的演变，因为大爆炸只有几个参数，其基本形式为六个。尽管是最简单的模型，但与早期宇宙测量相比，哈勃常数的直接延迟测量导致了所谓的$ H_0 $张力。据称，当将不同的宇宙学探针组合在一起时，迟到的时间分辨率被预定为失败。在这项工作中，我们以非常简单的模型来摇晃这种信念的基础。我们展示了如何使用CMB，BAO和SNE观测值组合而无需在$ H_0 $上使用任何先验的CMB，BAO和SNE观察，如何自然可以放松哈勃张力。通过包括哈勃常数的局部测量，可以进一步降低张力。
The standard model of cosmology, the $Λ$CDM model, describes the evolution of the Universe since the Big Bang with just a few parameters, six in its basic form. Despite being the simplest model, direct late-time measurements of the Hubble constant compared with the early-universe measurements result in the so-called $H_0$ tension. It is claimed that a late time resolution is predestined to fail when different cosmological probes are combined. In this work, we shake the ground of this belief with a very simple model. We show how, in the context of cubic vector Galileon models, the Hubble tension can naturally be relieved using a combination of CMB, BAO and SNe observations without using any prior on $H_0$ . The tension can be reduced even further by including the local measurement of the Hubble constant.
