The research to be carried out centers on solar radio astronomy. Specifically, decimetricbursts will be studied using the combined spectral, temporal, and spatial capabilities ofthe Owens Valley Solar Array (OVSA) and the Frequency Agile Solar Radiotelescope(FASR) Subsystem Testbed. The magnetic and plasma properties of the solar coronaabove active regions will also be explored, including elucidating the 3D structure of thecorona above active regions. In-depth studies of magnetic reconnection in both tworibbonflares and bursts with pulsations will be undertaken, and their relation to theacceleration of electrons that produce the radio and hard X-ray bursts will be evaluated.The OVSA instrument is a university-based solar-dedicated radio imaging array and theonly solar-dedicated radio instrument in the US. During the award period, thetesting/prototyping of technology for the Frequency Agile Solar Radiotelescope willbe continued. In addition, the data collected throughOVSA will made available to scientists world-wide as well as to undergraduates andgraduate students at the New jersey Institute of Technology for use in research projects.

将进行的研究以太阳射电天文学为中心。具体来说，分米波爆发将使用欧文斯谷太阳能电池阵列（OVSA）和频率捷变太阳射电望远镜（FASR）子系统测试床的综合光谱，时间和空间能力进行研究。活动区上方日冕的磁性和等离子体特性也将被探索，包括阐明活动区上方日冕的三维结构。将对涡卷耀斑和脉动爆发中的磁重联进行深入研究，并评估它们与产生射电和硬X射线爆发的电子加速的关系。OVSA仪器是一个基于大学的太阳专用射电成像阵列，也是美国唯一的太阳专用射电仪器。在授标期间，将继续对频率捷变太阳射电望远镜进行技术测试/原型制作。此外，通过OVSA收集的数据将提供给世界各地的科学家以及新泽西理工学院的本科生和研究生，用于研究项目。
