Parkes observations for project P892 semester 2018OCTS_03

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 项目瞄准银纬最高的天区，开展脉冲星（pulsar）与快速射电暴（fast radio bursts, FRBs）搜寻研究。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开展探测，可实现实时发现。在平方千米阵列（Square Kilometre Array, SKA）第一阶段的观测范式中，实时流式数据处理是核心需求，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。本项目所发现的脉冲星多为邻近闪烁源、间歇辐射源，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探测延迟仅约1秒，远快于传统的数月乃至数年周期；同时通过专用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探测快速射电暴的精确定位，这是识别其宿主星系的关键前提，进而破解快速射电暴的起源谜题，并挖掘其作为高精度宇宙学测量工具的多重应用价值。
