Hydrodynamics and Radiative Properties of Relativistic Jets

休斯，菲利普AST 96-17032 休斯博士将研究相对论天体物理流动的动力学，并计算这种流动的辐射特性，以与单碟和甚长基线干涉测量数据进行比较。 这项工作将围绕现有的代码进行，这些代码将得到改进和扩展。 该研究的目标是探索激波在弯曲流中的传播，以解决激波是否来自流和茧之间的反馈或来自中央发动机附近，以确定激波是否具有足够薄的结构来解释观察到的变化，以建立流的速度和密度场的现实参数化，并推断所观察到的射流的流型以区分中心发动机模型。

Hughes, Philip AST 96-17032 Dr. Hughes will study the dynamics of relativistic astrophysical flows and compute the radiative properties of such flows for comparison with single-dish and Very Long Baseline Interferometry data. The work will center around existing code which will be improved and extended. The goals of the study are to explore the propagation of shocks in curved flows, to address whether shocks arise from feedback between flow and cocoon or from near the central engine, to determine whether shocks have structure thin enough to explain observed variability, to establish realistic parameterizations of the velocity and density field of flows, and to infer flow patterns of observed jets to discriminate between central engine models.
