Self-Consistent Studies of Particle Acceleration In and Radiation Emission From Relativistic Outflows of GRBs

这个项目的目标是扩大我们对高能天体物理现象的理解，如粒子加速和辐射发射，应用于伽马射线暴(伽马射线暴)，这是宇宙中已知的最高能量的事件之一。涉及的物理过程密切相关，梅德韦杰夫博士将使用理论分析的基本原理、专门的数值模拟以及与观测数据的比较来研究它们之间的联系。这项工作的广泛影响包括对研究生和本科生的培训，以及通过开发互联网资源进行推广，该资源将向非专家解释无碰撞冲击物理学的概念和现状，以及应用于伽马射线爆发的相关过程，如辐射发射和粒子加速。

The goal of this project is to broaden our understanding of high-energy astrophysical phenomena, such as particle acceleration and radiation emission, in application to gamma-ray bursts (GRBs), which are among the most energetic events known in the universe. The physical processes involved are closely related and Dr. Medvedev will investigate their connections using first principles of theoretical analysis, dedicated numerical simulation, and comparison with observational data.Broader impacts of the work include training of graduate and undergraduate students, and outreach via development of an internet resource which will explain to non-experts the ideas and the current status of the physics of collisionless shocks and relevant processes such as radiation emission and particle acceleration in application to gamma-ray bursts.
