Parkes observations for project P892 semester 2018APRS_BPSR_59

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 项目以银纬极高的天区为观测目标，开展脉冲星与快速射电暴（fast radio bursts, FRBs）的搜寻工作。本项目采用优化后的图形处理器（Graphics Processing Unit, GPU）代码与超级计算集群执行搜寻任务，可实现实时发现成果。在平方公里阵列（Square Kilometre Array, SKA）一期建设与运行阶段，实时处理流式传入的观测数据是核心需求，因此本项目的技术方案可直接适配下一代望远镜的高数据率观测场景。本项目发现的脉冲星多为邻近的闪烁源、暂现源，以及处于特殊双星系统中的脉冲星。本项目发现快速射电暴的响应延迟仅约1秒，而非数月乃至数年；我们会通过专用的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预警信息。本项目的核心目标是实现已发现快速射电暴的精确定位，这一能力对于识别快速射电暴的宿主星系、揭开其前身天体的谜团，以及将其作为精密宇宙学测量工具加以利用均具有关键意义。
