This award will fund the continuation of a successful survey of white-dwarf supernova explosions (called "Type I") at telescopes in Arizona and Chile. The main goal of the work will be to compare low redshift (nearby) supernovae with their high-redshift (distant) counterparts, especially through observations in the infrared which can reduce the effects of dust. Under earlier funding from NSF, this group has assembled a large and homogeneous set of Type I supernovae light curves and spectra, developed original methods for using them using advanced statistical techniques, and addressed problems of cosmic expansion such as local flows, the Hubble constant, cosmic acceleration and the nature of the dark energy.The project is expected to advance the study of dark energy, which makes up most of the universe. Results from this survey will be incorporated into the undergraduate curriculum at Harvard, and students will be involved in the research. The award will also support ongoing efforts outreach and public education.

该奖项将用于继续对亚利桑那州和智利望远镜上的白矮星超新星爆炸(称为“I型”)进行成功的调查。这项工作的主要目标将是比较低红移(近)超新星和高红移(远)超新星，特别是通过红外观测可以减少尘埃的影响。在美国国家科学基金会的早期资助下，该小组组装了一套大型而均匀的I型超新星光曲线和光谱，开发了使用先进统计技术使用它们的原创方法，并解决了宇宙膨胀的问题，如局部流动、哈勃常数、宇宙加速和暗能量的性质。该项目有望推动对暗能量的研究，暗能量构成了宇宙的大部分。这项调查的结果将被纳入哈佛大学的本科课程，学生将参与这项研究。该奖项还将支持正在进行的努力、外联和公共教育。
