论文摘要
我们通过重建不同的现象学方法来测试IA型超新星的绝对绝对幅度的宇宙学意义，该方法可以证明可以证明不同的绝对幅度合理的不同现象学方法，但也基于宇宙空隙，修饰的重力模型和bin固定方案。在这项工作中考虑的所有情况下，我们都可以与标准$λ$ CDM模型的预期值吻合，也没有新物理学的证据。
We test the cosmological implications of a varying absolute magnitude of Type Ia supernovae using the Pantheon compilation, by reconstructing different phenomenological approaches that could justify a varying absolute magnitude, but also approaches based on cosmic voids, modified gravity models and a binning scheme. In all the cases considered in this work, we find good agreement with the expected values of the standard $Λ$CDM model and no evidence of new physics.
