Dr. Backer at the University of California, Berkeley will use a signal processor which he developed to search large areas of the sky for pulsars with millisecond periods. In addition to its search mode, the signal processor can be used for pulse timing of known pulsars and as a flexible spectrum analyzer. Research into pulsars with millisecond periods and the related binary pulsars is evolving rapidly. These objects have established new constraints on the internal structure of neutron stars and on neutron star magnetospheres. Pulse time-of-arrival measurements of these pulsars have had a tremendous impact on a number of branches of science: on high density matter physics, on Solar System ephemeris development, and on general relativity and cosmology. Dr. Backer's research is at the forefront of discovering more members of this important class of pulsars.

加利福尼亚大学伯克利分校的Backer博士将使用一个信号处理器，他开发了该信号处理器，以搜索毫秒毫秒的脉冲星。 除了其搜索模式外，信号处理器还可以用于已知脉冲星的脉冲正时，作为柔性光谱分析仪。 对具有毫秒毫秒和相关二元脉冲星的脉冲星的研究正在迅速发展。 这些物体已经建立了对中子恒星内部结构和中子恒星磁层的新约束。 这些脉冲星的脉搏时间测量对许多科学分支产生了巨大影响：高密度物理物理学，太阳系ephemeris发展以及一般相对论和宇宙学。 Backer博士的研究处于发现这一重要类Pulsars的更多成员的最前沿。
