论文摘要
宇宙学的绝对距离尺度测量一直是一个重要的任务。特别是,近年来,早期和晚期宇宙的测量结果之间的哈勃持续张力已成为宇宙学的新危机,该危机要求进行新的独立的绝对宇宙学距离测量。最近,报道了通过光谱测量法和回响映射测量视差距离至3C 273的结果。我们在此新闻和视图论文中对这种新颖方法评论。
The absolute distance scale measurements in cosmology have always been an important mission. In particular, in recent years, the Hubble constant tension between the measurements from early and late universe has become a new crisis for cosmology, which calls for new, independent absolute cosmological distance measurements. Recently, a result of measuring the parallax distance to 3C 273 through spectroastrometry and reverberation mapping was reported. We comment on this novel method in this News & Views paper.
