Parkes observations for project P892 semester 2018APRS_BPSR_05

SUPERBx looks at the highest Galactic latitudes in a search for pulsars and fast radio bursts (FRBs). We use optimised GPU codes and supercomputing to search for these, 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. Our pulsar discoveries are typically nearby scintillating sources, intermittent sources and those in interesting binary systems. Our FRB discoveries have discovery lags of ~1 second, rather than months/years and these feed rapid alerts to the world-wide follow-up community via a dedicated VOEvent format an Astronomer's Telegrams. The goal of this is to allow localisation of the discovered FRBs. 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 项目瞄准最高银道纬度区域，开展脉冲星 (pulsar) 与快速射电暴 (fast radio bursts, FRBs) 搜寻工作。本项目采用优化后的图形处理器 (Graphics Processing Unit, GPU) 代码与超级计算机开展搜寻，可实现实时发现。在平方公里阵列射电望远镜 (Square Kilometre Array, SKA) 一期工程阶段，实时处理传入数据至关重要，因此本工作可直接适配下一代望远镜的高数据率场景。本项目发现的脉冲星多为邻近的闪烁源、间歇源，以及处于具有研究价值的双星系统中的脉冲星。本项目发现快速射电暴的滞后时长约1秒，而非数月乃至数年；我们会通过专用VOEvent (VOEvent) 格式与《天文学家电报》 (Astronomer's Telegrams) 向全球后续观测社群快速推送警报。本项目的目标是实现已发现快速射电暴的精确定位，这对识别快速射电暴的宿主星系至关重要，进而破解其前身天体的谜题，并挖掘其作为精密宇宙学测量工具的多重应用价值。
