Finding radio pulsars has always been an extremely rewarding challenge and has led to Nobel Prize winning science. We are now entering a new era of radio astronomy and have new game changers, sensitive, wide-field-of-view imaging telescopes and massive compute resources, to search for extreme pulsars. Such pulsars, including pulsar-blackhole systems and sub-millisecond pulsars, cannot be found with traditional pulsar surveys, but provide us unique laboratories to test gravity theories at ultra-strong gravitational fields and probe the state of matter at supra-nuclear densities. In this project I will leverage the Australian Square Kilometre Array Pathfinder (ASKAP) to discover the most extreme pulsars in deep all-sky continuum surveys.

寻找射电脉冲星一直是一项非常有意义的挑战，并导致了诺贝尔奖得主的科学。我们现在正在进入射电天文学的新时代，有了新的游戏规则改变者，灵敏的，宽视场的成像望远镜和大量的计算资源，来搜索极端脉冲星。这样的脉冲星，包括脉冲星-黑洞系统和亚毫秒脉冲星，无法通过传统的脉冲星测量找到，但为我们提供了独特的实验室，可以在超强引力场下测试重力理论，并探测超核密度下的物质状态。在这个项目中，我将利用澳大利亚平方公里阵列探路者（ASKAP）在深全天连续体调查中发现最极端的脉冲星。
