宇宙膨胀:哈勃-勒梅特张力的迷你评论

Cosmic Expansion: A mini review of the Hubble-Lemaitre tension

Francis-Yan Cyr-Racine

摘要:

我们在这里提出一个闪电审查的地位哈勃勒梅特紧张。而不是讨论广泛的建议的解决方案在文献中发现,我们在这里集中的假设,以测量哈勃常数从宇宙微波背景和重子声学振荡数据一方面,从造父变星校准的距离阶梯另一方面。从这个讨论中,我们总结出两个重要的经验教训,告诉我们哪种基于物理的解决方案可以合理地解决这种紧张关系。

英文摘要:

We present here a lightning review of the status of the Hubble-Lemaître tension. Instead of discussing the broad array of proposed solutions found in the literature, we focus here on the assumptions made to measure the Hubble constant from cosmic microwave background and baryon acoustic oscillation data on the one hand, and from a cepheid-calibrated distance ladder on the other hand. From this discussion, we extract two important lessons that inform which kind of physics-based solutions could plausibly resolve this tension.
