Supernova remnants result when the ejecta of a supernova expands into the ambient interstellar medium, compresses it, and mixes with it. This expansion and mixing are extraordi.narily complex. The Principal Investigator proposes to observe and map nearby supernova remnants and to model them computa.tionally. The goal is to increase our understanding of the physical processes taking place in them, in particular to find out how and where synchrotron radio emission takes place in them and how this emission varies with time.

当超新星的喷射物膨胀到周围的星际介质中，压缩它，并与它混合时，就会产生超新星遗迹。这种扩张和混合是非同寻常的。不复杂。首席研究员建议观察和绘制附近超新星遗迹的地图，并通过计算建立它们的模型。目标是增加我们对它们中发生的物理过程的理解，特别是找出同步辐射是如何和在哪里发生的，以及这种辐射是如何随时间变化的。
