ASKAP Data Products for Project AS301 (A search for pulsar candidates in the sky area around OJ287): catalogues

The discovery of a pulsar with a small angular offset from the Blazar OJ287 would significantly increase the chances of the pulsar timing array projects detecting gravitational waves from a supermassive binary black hole binary system. A survey with Parkes found no such pulsar and so we plan to search deeper with the FAST telescope. However, FAST cannot cover (in a reasonable time) the necessary sky area and so we propose to use ASKAP to identify pointing directions in which there is a reasonable chance that a pulsar exists.

发现一颗与耀变体（Blazar）OJ287存在小角度偏移的脉冲星（pulsar），将显著提升脉冲星计时阵列（Pulsar Timing Array）项目探测超大质量双黑洞系统引力波的概率。帕克斯望远镜（Parkes）的巡天观测未发现此类脉冲星，因此我们计划使用500米口径球面射电望远镜（FAST）开展更深层次的搜寻工作。然而，FAST望远镜无法在合理时长内覆盖所需的天区范围，故我们提议借助澳大利亚平方千米阵探路者（ASKAP）望远镜识别存在脉冲星的高概率指向天区。
