Parkes observations for project P892 semester 2017APRS_BPSR_10

SUPERBx is an extension to the SUPERB survey which looks at the highest Galactic latitudes in a search for fast radio bursts (FRBs). We will focus our efforts at high Galactic latitudes where our previous work has shown FRB detectability to be as much as 4 times higher than in the plane. SUPERBx uses optimised GPU codes to search for pulsars and fast radio bursts (FRBs), making discoveries in real time. Handling our data as it comes in is essential for the SKA Phase I era so this work applies directly to the high-data rates of next generation telescopes. The FRBs discovered (we have already discovered four FRBs in this project) will have much more associated information than all previous detections. Firstly our discovery lag is ~1 second, rather than months/years. The Parkes observations will be shadowed by other radio telescopes (in particular the refurbished Molonglo which has now reached a level of performance where it has independently discovered 3 FRBs in 2016) to allow localisation of the discovered FRBs, and a host of optical and high-energy telescopes will then be triggered as appropriate. This is key for identifying FRB host galaxies, so as to solve the mystery of their progenitors and to exploit their many uses as tools for precision cosmology measurements.

SUPERBx是SUPERB巡天项目的扩展，旨在通过观测最高银纬区域寻找快速射电暴（FRBs）。我们将重点研究高银纬区域——此前研究表明，该区域的快速射电暴（FRB）探测率比银道面高4倍之多。SUPERBx采用优化的GPU代码搜索脉冲星和快速射电暴（FRBs），实现实时发现。在平方公里阵列射电望远镜（SKA）第一阶段时代，实时处理输入数据至关重要，因此本工作可直接应用于下一代望远镜的高数据率场景。本项目已发现4个FRBs，这些新发现的FRBs将比以往探测到的拥有更丰富的关联信息。首先，我们的发现延迟约为1秒，而非数月或数年。帕克斯望远镜的观测将由其他射电望远镜（尤其是翻新后的莫隆洛望远镜——其性能已达到可独立探测FRBs的水平，2016年曾独立发现3个FRBs）进行协同观测，以实现FRBs的定位；随后将适时触发大量光学及高能望远镜开展后续观测。这对于确定FRB的宿主星系至关重要，进而可解开其起源之谜，并充分利用FRBs作为精密宇宙学测量工具的多种用途。
