Parkes observations for project P892 semester 2018APRS_04

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项目聚焦于银纬最高的天区，用于搜寻脉冲星（pulsar）与快速射电暴（Fast Radio Bursts, FRBs）。本项目采用优化后的图形处理器（Graphics Processing Unit, GPU）代码与超级计算机开展搜寻工作，可实时实现天体发现。对于平方公里阵列（Square Kilometre Array, SKA）第一阶段而言，实时处理流式传入的数据至关重要，因此本项目的工作可直接适配下一代望远镜的高数据速率场景。本项目发现的脉冲星多为邻近的闪烁源、间歇源，以及处于各类有趣双星系统中的脉冲星。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（Virtual Observatory Event）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，其核心目标是实现已发现快速射电暴的精确定位。这是识别快速射电暴宿主星系的关键，进而破解其起源之谜，并将其作为精密宇宙学测量工具加以充分利用。
