Millisecond Pulsar Search

加州大学伯克利分校的Backer博士将使用他开发的信号处理器在天空的大片区域搜索毫秒周期的脉冲星。除了它的搜索模式，信号处理器可以用于脉冲定时已知脉冲星和作为一个灵活的频谱分析仪。对毫秒周期脉冲星和相关的双星脉冲星的研究进展迅速。这些天体建立了中子星内部结构和中子星磁层的新约束。这些脉冲星的脉冲到达时间测量对许多科学分支产生了巨大的影响：高密度物质物理学、太阳系星历的发展、广义相对论和宇宙学。贝克博士的研究处于发现更多这类重要脉冲星成员的前沿。

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.
