论文摘要
我们表明，通过普朗克卫星和光度距离数据获得的CMB各向异性功率光谱的组合分析同时排除了平坦的宇宙和宇宙学常数，价格为$ 99 \％$ cl。当将Planck与三个不同的数据集相结合时，这些结果分别成立：Riess等人的Hubble常数的两个确定。 2019年和Freedman等。 2020年，以及高红移超新星类型的万神殿目录。我们得出的结论是，要么LCDM需要用不同的模型代替，否则有很大的但仍未发现的系统学。我们的结果要求进行新的观察，并刺激对替代理论模型和解决方案的研究。
We show that a combined analysis of CMB anisotropy power spectra obtained by the Planck satellite and luminosity distance data simultaneously excludes a flat universe and a cosmological constant at $99 \%$ CL. These results hold separately when combining Planck with three different datasets: the two determinations of the Hubble constant from Riess et al. 2019 and Freedman et al. 2020, and the Pantheon catalog of high redshift supernovae type-Ia. We conclude that either LCDM needs to be replaced by a different model, or else there are significant but still undetected systematics. Our result calls for new observations and stimulates the investigation of alternative theoretical models and solutions.
