Parkes observations for project P892 semester 2016OCTS_BPSR_02

SUPERBx is an extension to the SUPERB survey which looks at the highest Galactic latitudes in a search for fast radio bursts (FRBs). Our most recent results show that there is a strong Galactic latitude dependence to FRB detectability with the detection rate being 4 times higher ~45 degrees and higher above the plane; this is where SUPERBx will focus its efforts from now on. 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调查的扩展，旨在搜寻银纬最高区域的快速射电暴（FRBs）。我们最新的研究结果表明，FRB的可探测性与银纬存在强烈相关性——在银盘以上约45度及更高纬度区域，其探测率高出4倍；这正是SUPERBx今后工作的重点方向。SUPERBx采用优化的GPU代码实时搜索脉冲星和快速射电暴（FRBs），实现实时发现。在平方公里阵列望远镜（SKA）第一阶段时代，实时处理传入数据至关重要，因此这项工作直接适用于下一代望远镜的高数据率场景。该项目已发现4个FRBs，这些新发现的FRBs比以往所有探测结果拥有更多关联信息：首先，发现滞后时间仅约1秒，而非数月或数年；其次，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2016年已独立发现3个FRBs，性能达到相应水平）同步观测，以便对发现的FRBs进行定位；随后，将适时触发一系列光学及高能望远镜开展后续观测。这对于识别FRB的宿主星系、破解其起源之谜以及将其作为精确宇宙学测量工具具有关键意义。
