摘要
In recent years, the Hubble tension has emerged as one of the most perplexing enigmas within the realm of cosmology[1]. This incongruity suggests the tantalizing prospect of new physics beyond the standard ΛCDM model, leading to the proposal of diverse extended cosmological models. At the same time, there is a pressing demand for novel cosmological tools to mediate the Hubble tension. The gravitational-wave(GW) standard siren has been put forth as a promising cosmological probe for resolving the Hubble tension, provided that the redshift of the GW source is known, as exemplified in ref. [2].
