摘要
我们提出了天体物理喷流的全三维(3-D)模拟结果。这些努力使用PLUTO代码(Mignone et al. 2007)在一个高度并行的环境中运行,用于流体动力学、磁流体动力学(MHD)、相对论流体动力学(RHD)和相对论磁流体动力学(RMHD)模拟。在这项工作中,我们专注于RMHD模拟,但也提出了基于RHD模拟后处理的15ghz无线电通量估计,以显示天体物理射流的无线电发射。关键词:喷流,活动星系,耀发星,星系团内介质,非线性动力学,等离子体物理,计算流体动力学,相对论,磁化流体流动。
Large-Scale Hydrodynamic Simulations of Astrophysical Jets
We present results of fully three-dimensional (3-D) simulations of astrophysical jets. These ef-
forts use the the PLUTO code (Mignone et al. 2007) run in a highly parallel environment for the
hydrodynamic, magneto-hydrodynamic (MHD), relativistic hydrodynamic (RHD), and relativis-
tic, magnetohydrodynamic (RMHD) simulations. In this work, we focus on RMHD simulations,
but also present estimations of the 15 GHz radio flux based on RHD simulations post-processed
to show the radio-emission from the astrophysical jets.
Keywords: jets, active galaxies, blazars, intracluster medium, non-linear dynamics, plasma as-
trophysics, computational fluid dynamics, relativistic, magnetized fluid flows.
