论文摘要
我们结合了基于Cepheids-Sn IA，Trgb-Sn IA，Miras-Sn IA，Masers，Masers，Tully Fisher，表面亮度波动，SN II，SN II，Time-Delay镜头，标准的SIRENS和$γ$ -2 $ -2 $ - 射线的衰减，获得了我们最佳{\ IT Optivical { $ h_0 = 72.94 \ pm0.75 $ km/s/mpc在68 \％cl。与$λ$ CDM型号相比，这是$5.9σ$张力，因此，我们评估了它对可以减轻张力的扩展深色能量宇宙学模型的影响。我们在$ W $ CDM方案中找到了幻影暗能量状态方程的$4.9σ$证据，在$ W_0W_A $ CDM模型中排除的宇宙常数超过$3σ$，以及在iDEDECARIO中遇到的暗物质和暗能量之间的耦合。最后，我们检查结果的鲁棒性，并引用了哈勃常数的另外两个组合。获得{\ IT超保守}估计值，$ H_0 = 72.7 \ pm 1.1 $ km/s/mpc在68 \％cl中获得删除CepheIDS-SN IA和基于时间播放镜头的测量结果，并确认了新物理学的证据。
We combine 23 Hubble constant measurements based on Cepheids-SN Ia, TRGB-SN Ia, Miras-SN Ia, Masers, Tully Fisher, Surface Brightness Fluctuations, SN II, Time-delay Lensing, Standard Sirens and $γ$-ray Attenuation, obtaining our best {\it optimistic} $H_0$ estimate, that is $H_0=72.94\pm0.75$ km/s/Mpc at 68\% CL. This is in $5.9σ$ tension with the $Λ$CDM model, therefore we evaluate its impact on the extended Dark Energy cosmological models that can alleviate the tension. We find more than $4.9σ$ evidence for a phantom Dark Energy equation of state in the $w$CDM scenario, the cosmological constant ruled out at more than $3σ$ in a $w_0w_a$CDM model and more than $5.7σ$ evidence for a coupling between Dark Matter and Dark Energy in the IDE scenario. Finally, we check the robustness of our results, and we quote two additional combinations of the Hubble constant. The {\it ultra-conservative} estimate, $H_0=72.7\pm 1.1$ km/s/Mpc at 68\% CL, is obtained removing the Cepheids-SN Ia and the Time-Delay Lensing based measurements, and confirms the evidence for new physics.
