Dr. Backer's research covers a range of studies in the general field of pulsar astrophysics. There are two principal foci: the development of new hardware for searching for pulsars with fast periods; and surveys to discover other interesting objects in this class. A set of these pulsars will be monitored as celestial clocks for precision experiments. Pulsars with millisecond periods and binary pulsars probably form a distinct class of neutron stars that have rotational periods which are processed by angular momentum transfer from a companion star. The solitary millisecond pulsars have an uncertain past, but may fit the binary scenario if evaporation of a companion can proceed to completion. Dr. Backer's research is involved in both finding new members of this class of pulsars, and in using millisecond pulsars as celestial clocks for precision measurements.

Backer博士的研究涵盖了Pulsar天体物理学一般领域的一系列研究。 有两个主要焦点：开发用于搜索具有快速时期的脉冲星的新硬件；并调查以发现此类中其他有趣的对象。 一组这些脉冲星将作为天钟进行监测，以进行精确实验。 具有毫秒毫秒和二元脉冲星的脉冲星可能形成了一类不同的中子星，它们具有旋转周期，这些旋转周期是通过伴侣恒星的角动量转移来处理的。 单独的毫秒脉冲星有不确定的过去，但是如果同伴的蒸发可以完成，则可能适合二进制方案。 Backer博士的研究既参与寻找此类脉冲星的新成员，又要将毫秒的脉冲星作为天钟进行精确测量。
