This program will undertake a series of observational and theoretical studies of the powerful jets which are seen to emerge at close to the speed of light from the centers of active galaxies and quasars, and also from some x-ray binary systems known as micro-quasars within our own Galaxy. It will attempt to answer basic questions about the jets and their central engines, by exploiting the information in the linear and circular polarization of the radio emission. The observations will yield other fundamental information such as the mix of positrons and protons in the jet, and the jet's kinetic luminosity.Broader impacts of the work include training of undergraduate and graduate students, and working with local teachers and students in using the campus 24" telescope.

该计划将对强大的喷流进行一系列观测和理论研究，这些喷流以接近光速的速度从活跃星系和类星体的中心以及我们银河系内被称为微类星体的一些 X 射线双星系统中出现。 它将尝试通过利用无线电发射的线性和圆偏振信息来回答有关喷气式飞机及其中央发动机的基本问题。 观测结果将产生其他基本信息，例如喷流中正电子和质子的混合情况，以及喷流的动光度。这项工作的更广泛影响包括培训本科生和研究生，以及与当地教师和学生合作使用校园 24 英寸望远镜。
