The objective of this program is to further our understanding both of supernovae as astrophysical objects and of their use as a powerful cosmological probe. Broader impacts of the work include research training of graduate students and a postdoctoral scholar, and outreach via public talks and popular books and articles. The research will advance knowledge of Dark Energy and other cosmological parameters by employing supernovae as a measure of the expansion history of the Universe. The study of supernovae in the infrared, as will be done here, is especially promising given the excellent standard candle behavior as compared to visible wavelengths. The work will provide new insights on Dark Energy, the discovery of which was pioneered by this group.

该计划的目的是进一步了解超新星作为天体物理学对象和它们作为强大的宇宙学探测器的用途。 工作的更广泛影响包括研究生和博士后学者的研究培训，以及通过公开演讲和流行书籍和文章进行宣传。 这项研究将通过使用超新星作为宇宙膨胀历史的衡量标准来推进对暗能量和其他宇宙学参数的认识。由于与可见光波段相比，标准烛光的表现非常出色，因此，在红外波段对超新星的研究，就像这里将要做的那样，特别有希望。 这项工作将为暗能量提供新的见解，暗能量的发现是由这个小组开创的。
