我们根据各种假设和有关星形成历史的最新数据讨论超新星的宇宙历史。我们表明，超新星的速率随红移的函数可用于对祖细胞模型，恒星形成历史以及灰尘遮挡的重要性放置重大约束。我们证明，存在宇宙常数的当前观察指示仅仅是不同红移间隔不同祖细胞类别的主导地位的伪像。
We discuss the cosmic history of supernovae on the basis of various assumptions and recent data on the star formation history. We show that supernovae rates as a function of redshift can be used to place significant constraints on progenitor models, on the star formation history, and on the importance of dust obscuration. We demonstrate that it is unlikely that the current observational indications for the existence of a cosmological constant are merely an artifact of the dominance of different progenitor classes at different redshift intervals.
