Parkes observations for project P892 semester 2018APRS_14

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 项目聚焦于银道坐标系最高纬度区域，开展脉冲星（pulsars）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）代码与超级计算资源开展观测，可实现信号的实时发现。鉴于平方公里阵列（Square Kilometre Array, SKA）第一阶段的观测对实时流式数据处理提出了核心要求，本项目的工作方法可直接适配下一代望远镜的高数据率观测场景。本项目所发现的脉冲星多为邻近闪烁源、间歇源，以及处于特殊双星系统中的天体。本项目发现快速射电暴的响应时延仅约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，以此实现已发现快速射电暴的精确定位。这一精准定位环节是识别快速射电暴宿主星系的关键前提，进而可破解其起源的未解之谜，并充分利用其作为精密宇宙学测量工具的多重应用价值。
