This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This is a program to perform a multi-wavelength study of Gamma Ray Bursts (GRBs) to: 1. Systematically analyze GRB afterglow data, and clearly identify emission components that have distinct physical origins; 2. Perform detailed modeling of broadband, multi-component afterglows using a sophisticated external forward shock model; 3. Analyze the GRB prompt emission data collected by Swift/BAT and Fermi/GBM, and investigate the validity of various empirical correlations; and 4. Model the broad band prompt emission of GRBs. Data will come from the Swift and Fermi space missions, and from HESS and VERITAS on the ground.

该奖项是根据2009年美国复苏和再投资法案(公共法律111-5)资助的。这是一个对伽马射线暴(GRB)进行多波长研究的项目，目的是：1.系统分析伽马射线暴余辉数据，清楚地识别具有不同物理来源的发射成分；2.使用复杂的外部前向激波模型对宽带、多组分余辉进行详细建模；3.分析SWIFT/BAT和FERMI/GBM收集的伽马射线暴即时发射数据，并调查各种经验关联的有效性；以及4.对伽玛射线暴的宽带即时发射进行建模。数据将来自SWIFT和费米太空任务，以及地面上的Hess和Veritas。
