Backer, DonaldUniversity of California, BerkeleyAST 98-20662Dr. Backer will carry out studies of Sgr A* and the Crab nebula and pulsar using a variety of radio telescopes and instrumentation. The studies are unified by the theme of high energy plasma astrophysics and the common technique of using distortions in the interstellar medium as probes of the nature of the object. Studies of the radio source at the galactic center, Sgr A* will include imaging, investigations of the nature of its temporal variability, and the use of its proper motions in dynamical studies. Studies of the Crab nebula and pulsar rely on interpreting pulsar signals that propagate through the interstellar medium to study issues such as the structure of the magnetic field structure in parts of the Galaxy, and the intrinsic properties of the pulsars themselves.

Backer，唐纳德加州大学伯克利分校AST 98-20662博士。 Backer 将使用各种射电望远镜和仪器对人马座 A*、蟹状星云和脉冲星进行研究。 这些研究以高能等离子体天体物理学的主题和利用星际介质中的扭曲作为物体性质探针的常用技术为统一主题。 对银河系中心射电源 Sgr A* 的研究将包括成像、对其时间变化性质的研究以及在动力学研究中使用其自行。 对蟹状星云和脉冲星的研究依赖于解释通过星际介质传播的脉冲星信号来研究银河系部分地区的磁场结构以及脉冲星本身的固有特性等问题。
