Parkes observations for project P892 semester 2018OCTS_BPSR_06

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 聚焦银纬最高的天区，搜寻脉冲星与快速射电暴（fast radio bursts, FRBs）。我们采用优化后的GPU（图形处理器）代码与超级计算机开展搜寻工作，可实时完成探测发现。在平方公里阵列望远镜（Square Kilometre Array, SKA）第一阶段的观测范式中，实时处理传入数据至关重要，因此本项工作可直接适配下一代望远镜的高数据率场景。我们所发现的脉冲星通常为邻近的闪烁源、间歇源，以及处于值得关注的双星系统中的脉冲星。我们的FRB探测延迟仅约1秒，而非数月乃至数年，并通过专用的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警报。此举旨在实现已发现FRB的定位，这对于识别其宿主星系、破解其起源之谜，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。
