Parkes observations for project P892 semester 2018APRS_12

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项目瞄准最高银纬区域，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开展搜寻，可实现实时探测与发现。在平方公里阵列（Square Kilometre Array, SKA）第一阶段的观测范式中，实时处理流式数据是核心要求，因此本项目的技术方案可直接适配下一代射电望远镜的高数据速率场景。本项目发现的脉冲星多为邻近闪烁源、间歇辐射源，以及处于具有重要科研价值的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，远快于传统的数月乃至数年周期；我们会通过专用VOEvent格式与《天文学家电报》（Astronomer's Telegrams）向全球后续观测社群快速发布警报。此举的核心目标是实现已发现快速射电暴的定位。这一定位机制是识别快速射电暴宿主星系的关键，进而能够破解其起源之谜，并挖掘其作为精确宇宙学测量工具的多重应用价值。
