Parkes observations for project P892 semester 2015APRS_BPSR_09

SUPERBx is an extension to the SUPERB survey which looks at the highest Galactic latitudes in a search for fast radio bursts (FRBs). Recent results show that there is a strong latitude dependence to FRB detectability so SUPERBx will search above 25 degrees in Galactic latitude. It will use 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 will have much more associated information than all previous detections. Firstly the discovery lag will be ~1 second, rather than months/years. The Parkes observations will be shadowed by other radio telescopes (Molonglo, GMRT, MWA) to allow, for the first time, localisation of 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.

SUPERBx是SUPERB巡天（SUPERB survey）的扩展项目，旨在针对银道面最高纬度区域开展快速射电暴（fast radio burst, FRB）搜寻。近期研究结果表明，快速射电暴的可探测性存在显著的银纬依赖性，因此SUPERBx将瞄准银纬25度以上的天区开展搜寻工作。该项目将采用优化后的图形处理器（Graphics Processing Unit, GPU）代码开展脉冲星与快速射电暴搜寻，实现实时发现。在平方公里阵列（Square Kilometre Array, SKA）第一阶段的观测范式下，实时处理传入数据至关重要，因此本项目的工作可直接适配下一代望远镜的高数据率场景。本次发现的快速射电暴将拥有远超此前所有探测结果的关联信息：其一，发现延迟仅约1秒，而非数月乃至数年。帕克斯（Parkes）望远镜的观测将得到莫龙戈洛（Molonglo）、巨型米波射电望远镜（GMRT）与默奇森宽场阵列（MWA）的协同覆盖，从而首次实现快速射电暴的定位；随后将根据实际需求触发一系列光学与高能望远镜开展后续观测。这是确定快速射电暴宿主星系、破解其起源之谜的核心关键。
