Interstellar Scattering in Radio Astronomy

小行星9414144 Rickett和Coles博士将研究无线电波辐射穿过星际等离子体时的散射。 这项研究的动机有两个：首先是为了了解散射，从而为射电天文学家预测星际波传播的扭曲效应;其次是为了记录扭曲和散射，并将其解释为研究遥远的电离星际介质的一种方式。 在第一种情况下，散射会给射电天文学家带来银河系的观测问题;在第二种情况下，散射的细节提供了一个信号，可以用来远程探测非常弥散的星际等离子体的特性。

9414144 Rickett Drs. Rickett and Coles will study the scattering of radiowavelength radiation as it passes through the interstellar plasma. The motivation for the research is twofold: first to understand the scattering and so predict the distorting effects of interstellar wave propagation for radio astronomers; second to record the distortions and scattering and to interpret them as a way of studying the distant ionized interstellar medium. In the first case the scattering causes a galactic seeing problem for radio astronomers; in the second case the details of the scattering provide a signal which can be used to remotely probe the characteristics of the very diffuse interstellar plasma.
