Parkes observations for project P892 semester 2017OCTS_BPSR_12

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，旨在通过观测最高银纬区域搜寻快速射电暴（FRBs）。我们将重点观测高银纬区域——此前研究表明，该区域的FRB探测概率较银道面高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。实时处理传入数据对于平方公里阵列望远镜一期（SKA Phase I）时代至关重要，因此本工作可直接适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将比以往所有探测结果包含更丰富的关联信息。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得到其他射电望远镜的协同支持——尤其是经过翻新的莫隆洛望远镜（其性能已达独立发现3个FRBs的水平），从而实现对新发现FRBs的定位；随后，大量光学及高能望远镜将根据需要被触发观测。这对于确定FRB的宿主星系至关重要，进而有助于解开其起源之谜，并将其作为精密宇宙学测量工具加以充分利用。
