Parkes observations for project P892 semester 2017OCTS_BPSR_18

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，专注于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——此前工作显示，该区域的快速射电暴探测率比银道面高出多达3倍。SUPERBx采用优化的GPU代码搜索脉冲星与快速射电暴，实现实时发现。实时处理传入数据对于平方公里阵列（Square Kilometre Array, SKA）第一阶段至关重要，因此本工作可直接适配下一代望远镜的高数据率需求。已发现的快速射电暴（本项目已发现5个）将比以往所有探测结果包含更丰富的关联信息：首先，发现延迟仅约1秒，而非数月或数年；其次，帕克斯（Parkes）望远镜的观测将由其他射电望远镜（尤其是翻新后的莫朗格洛（Molonglo）望远镜，其性能已达可独立发现3个快速射电暴的水平）同步观测，以实现对新发现快速射电暴的定位，随后将酌情触发一系列光学及高能望远镜。这对于识别快速射电暴的宿主星系至关重要，进而解开其起源之谜，并利用其作为精密宇宙学测量工具的多种用途。
