Particle Energization and Radiation in Relativistic Jets and Accretion Flows

这个项目将研究相对论喷流和吸积流中的粒子能量和辐射。它将把单胞粒子(PIC)运动学模拟应用于天体物理，特别是伽马射线暴和类星体喷流中的剪切流边界层，以及低光度活动星系核中的磁旋转不稳定性。其目标是增强磁流体动力计算机代码，使之包括“亚格子物理”。这项工作的更广泛影响包括对本科生和研究生的培训，以及开发先进的模拟方法，这些方法将在从天体物理学到激光等离子体相互作用和聚变的许多学科中有用。高中生将在暑期接受辅导。

This program will study particle energization and radiation in relativistic jets and accretion flows. It will apply particle-in-cell (PIC) kinematic simulations to astrophysics, in particular to the shear flow boundary layer in gamma ray bursts and quasar jets, and to the magneto-rotational instabilities in low-luminosity active galactic nuclei. The goal is to enhance magneto-hydrodynamic computer codes to include `subgrid physics'. Broader impacts of the work include training of undergraduate and graduate students, and development of advanced simulation methods that will be useful across many disciplines, from astrophysics to laser plasma interactions and fusion. High school students will be mentored during the summer.
