This award will support a project to obtain and analyze time-series data at infrared wavelengths. There are many advantages that infrared observations have over studies at visible wavelengths. These include better data on cool stars, such as red extragalactic transients and young stars, and amelioration of the effects of interstellar dust. The goals of this project are several: characterization of variability using large existing and proposed datasets; a targeted campaign on extragalactic cluster environments; a study of roughly 100 pulsating variables (RR Lyrae, Cepheids, and Miras); a systematic study and analysis of Type Ia and Type II-P supernovae in the infrared; and rapid observations of several gamma-ray bursts.The researchers will create a web portal to rapidly disseminate the results of this study to the astronomical community and to the general public. In addition, the team will make almost seven years of historical infrared time-domain data public with the archive and web portal. Finally, Dr. Bloom will be actively engaged in mentorship of the undergraduate students, graduate students and postdoctoral scholars involved in the project.

该奖项将支持一个项目，以获得和分析红外波长的时间序列数据。 红外线观测比可见光波长的研究有许多优点。 这些包括更好的冷恒星数据，如红色河外瞬变和年轻恒星，以及星际尘埃影响的改善。 该项目的目标有几个：使用现有和拟议的大型数据集描述变异性;针对河外星系团环境开展有针对性的活动;研究大约100个脉动变量（天琴座RR、造父变星和Miras）：在红外线中对Ia型和II-P型超新星的系统研究和分析;研究人员将创建一个门户网站，向天文学界和公众迅速传播这项研究的结果。 此外，该团队还将通过档案和门户网站公开近七年的历史红外时域数据。 最后，布鲁姆博士将积极参与指导参与该项目的本科生、研究生和博士后学者。
