The Principal Investigator (PI) will study thermal and nonthermal radio emission from solar flares through a combination of high resolution radio observations and sophisticated theoretical modeling. The PI's project team intends to develop new analytical methods and software tools for processing imaging radio spectroscopy data, in order to enhance the scientific output of existing radio observatory instruments (which are currently being actively upgraded), as well as the output of future instruments. The PI plans to develop a number of new models to exploit the latest observations and theories, and to create new methods for forward-fitting of radio spectroscopic imaging data and for measuring the diagnostics of high-energy electrons and plasma parameters in solar flaring regions. The PI's forward-fitting inversion methods, when combined with high-resolution imaging spectroscopy data, will enable the solar community to derive the key physical parameters of flares on dynamic time scales with unprecedented spatial resolution. Such investigations will directly address the fundamental questions of magnetic reconnection and particle acceleration processes in solar physics. This activity will include enhance scientific understanding throughout the discipline of astrophysics, since the processes of energy release and charged particle acceleration are common to most astrophysical systems. An increased understanding of the physics of energy release, transformation, and transfer in the solar atmosphere is directly applicable to space weather forecasting. The user-friendly software developed by the project team will be made widely available to the solar and space weather communities through the internet-based "SolarSoft" repository. The team will be actively involved in teaching, training, and learning through the Center for Solar-Terrestrial Research (CSTR) at the New Jersey Institute of Technology. The software tools created in this project will be widely used in graduate courses taught at CSTR in solar physics, radio astronomy, and plasma physics.

首席研究员（PI）将通过高分辨率无线电观测和复杂的理论建模的组合研究太阳耀斑的热和非热射射发射。 PI的项目团队打算开发新的分析方法和软件工具来处理成像无线电光谱数据，以增强现有无线电天文台仪器的科学输出（目前正在积极升级）以及未来工具的输出。 PI计划开发许多新模型来利用最新的观察值和理论，并创建新方法，用于拟合无线电光谱成像数据，并测量太阳能燃料区域中高能电子和等离子体参数的诊断。当与高分辨率成像光谱数据结合使用时，PI的前拟合反演方法将使太阳能群落能够在动态时间尺度上以前所未有的空间分辨率得出耀斑的关键物理参数。这样的研究将直接解决太阳能物理学中磁重新连接和颗粒加速过程的基本问题。由于能量释放和带电的颗粒加速度对于大多数天体物理系统来说是共同的，因此该活动将包括在整个天体物理学的整个学科中增强科学理解。对太阳大气中能量释放，转化和转移的物理学的了解直接适用于太空天气预报。项目团队开发的用户友好软件将通过基于Internet的“ Solarsoft”存储库广泛地向太阳能和太空天气社区广泛使用。该团队将通过新泽西理工学院的太阳能研究中心（CSTR）积极参与教学，培训和学习。该项目中创建的软件工具将被广泛用于在太阳能物理，射电天文学和等离子体物理学的CSTR教授的研究生课程中。
