Parkes observations for project P1090 semester 2020OCTS_05

We propose to search for millisecond pulsars (MSPs) in an annular region around Blazar OJ 287, the most promising candidate to host a nano-Hz gravitational wave (GW) emitting supermassive black hole binary (SMBHB). We plan to use the Parkes multibeam receiver to search for MSPs in the sky region around OJ 287. The proposed survey area of 143 square degrees is expected to yield at least one and possibly three MSPs. The observing strategy ensures that detected MSPs will be most sensitive to GWs from the proposed SMBHB in OJ 287. The timing of such MPSs should allow us to probe the properties of OJ 287 in the GW window.

本研究拟在耀变体OJ 287周围的环形天区搜寻毫秒脉冲星（millisecond pulsars, MSPs）。OJ 287是目前最具潜力的候选天体，其宿主系统为一颗能够辐射纳赫兹引力波（gravitational wave, GW）的超大质量双黑洞（supermassive black hole binary, SMBHB）。我们计划使用帕克斯多波束接收机（Parkes multibeam receiver）对OJ 287周边的天区开展毫秒脉冲星搜寻工作。本次拟开展的巡天覆盖面积达143平方度，预计至少可探测到1颗，最多或可发现3颗毫秒脉冲星。本次观测策略可确保，被探测到的毫秒脉冲星将对OJ 287内拟研究的超大质量双黑洞所产生的引力波具备最高灵敏度。通过对这类毫秒脉冲星的计时观测，我们能够在引力波窗口中探究OJ 287的相关物理特性。
