Parkes observations for project P1006 semester 2019APRS_38

We propose observations with the ultra-wide-bandwidth, low-frequency receiver installed at the Parkes telescope to carry out the first ultra-high time resolution, coherently de-dispersed search for pulsars in globular clusters. We have chosen the 11 most likely clusters for new discoveries. These clusters all have at least three pulsars already known allowing us to have a precise estimate of the pulsar dispersion measures and our observations will provide the first ultra-wide-bandwidth observation of these pulsars. Our observing strategy will enable us to search for extremely narrow pulsars and even pulsars with sub-millisecond periods.

我们提出利用帕克斯望远镜搭载的超宽带低频接收器开展观测，以首次实现对球状星团中脉冲星的超高时间分辨率相干去色散搜索。我们选取了11个最有可能产生新发现的星团，这些星团均已发现至少三颗脉冲星，使我们能够精确估计脉冲星的色散量；同时，本次观测将为这些脉冲星提供首次超宽带观测数据。我们的观测策略能够支持搜索极窄脉冲星，甚至是亚毫秒周期的脉冲星。
