Parkes observations for project P892 semester 2018OCTS_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 项目瞄准最高银纬天区，搜寻脉冲星与快速射电暴（Fast Radio Bursts, FRBs）。本项目采用经过优化的图形处理器（Graphics Processing Unit, GPU）代码与超级计算技术开展搜寻工作，可实现目标的实时发现。在平方公里阵列（Square Kilometre Array, SKA）第一阶段的运行范式中，实时处理流入数据是核心要求，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需求。本项目发现的脉冲星多为邻近的闪烁源、间歇性辐射源，以及处于特殊双星系统中的天体。本项目发现的快速射电暴的发现延迟仅约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警报。开展此类快速警报推送工作的核心目标，是实现已发现快速射电暴的定位；这一环节是识别其宿主星系的关键，进而得以解开快速射电暴的起源之谜，并将其作为精密宇宙学测量的工具，充分发挥其多方面应用价值。
