Parkes observations for project P982 semester 2018OCTS_04

We propose observations with the ultra-wide-bandwidth, low frequency receiver installed at the Parkes telescope to carry out the first coherently de-dispersed search for new pulsars in Southern globular clusters. We have chosen the three most likely clusters for new discoveries. We propose to observe each cluster from rise-to-set and will process the resulting data to study the known pulsars (allowing us, for the first time, to study the wide-band properties of their signal), whilst also looking for currently unknown pulsars. We note that the first black-hole--pulsar binary system is likely to be found in a globular cluster environment.

本研究拟利用安装于帕克斯（Parkes）望远镜的超宽带宽低频接收机，开展南天球状星团内新脉冲星的首次相干去色散搜索。我们遴选了最有望实现新发现的三个星团作为观测目标。我们计划对每个星团开展从升起到落下的全时段观测，并将对所得数据进行处理：一方面研究已知脉冲星（这将使我们首次得以研究其信号的宽带特性），同时同步搜寻当前尚未被发现的脉冲星。我们注意到，首个黑洞-脉冲星双星系统极有可能在球状星团环境中被发现。
