Parkes observations for project P892 semester 2017OCTS_BPSR_54

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 3 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 five 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) 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，旨在观测最高银纬区域以搜寻快速射电暴（fast radio bursts, FRBs）。我们将重点研究高银纬区域，此前研究表明该区域的FRB探测率比银道面高出3倍之多。SUPERBx采用优化的GPU代码搜寻脉冲星与快速射电暴（FRBs），实现实时发现。在平方公里阵列（SKA）第一阶段时代，实时处理传入数据至关重要，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5个FRBs，这些新发现的FRBs携带的关联信息远多于以往所有探测结果。首先，我们的发现延迟仅约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同步跟踪（尤其是翻新后的莫隆戈洛望远镜，其性能已达独立发现3个FRBs的水平），以便对发现的FRBs进行定位；随后，相应的光学及高能望远镜将被触发观测。这对于识别FRB的宿主星系至关重要，有助于解开其起源之谜，并将其作为精密宇宙学测量的工具加以利用。
