Parkes observations for project P1090 semester 2020OCTS_03

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.

我们提出在耀变体（Blazar）OJ 287周围的环形天区中搜寻毫秒脉冲星（millisecond pulsars, MSPs）——OJ 287是目前最具潜力的拥有发射纳赫兹引力波（nano-Hz gravitational wave, GW）的超大质量黑洞双星（supermassive black hole binary, SMBHB）的候选天体。本研究计划利用帕克斯多波束接收机（Parkes multibeam receiver）在OJ 287周边天区开展MSPs搜寻工作。此次拟定的巡天天区面积为143平方度，预计至少能发现1颗，最多或可探测到3颗MSPs。该观测策略可确保所探测到的MSPs对OJ 287中拟定的SMBHB产生的引力波具备最高灵敏度。通过对这类MSPs的计时观测，我们将能够在引力波窗口下探究OJ 287的相关性质。
