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.

这个项目将研究相对论喷流和吸积流中的粒子散射和辐射。 它将把粒子-单元（PIC）运动学模拟应用于天体物理学，特别是伽马射线爆发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。目标是加强磁流体动力学计算机代码，使之包括“次网格物理学”。 这项工作的更广泛影响包括本科生和研究生的培训，以及先进模拟方法的开发，这些方法将在许多学科中有用，从天体物理学到激光等离子体相互作用和聚变。 高中生将在夏季接受辅导。
