Parkes observations for project P892 semester 2018APRS_09

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 项目聚焦银纬最高的天区，开展脉冲星（pulsars）与快速射电暴（fast radio bursts, FRBs）的搜寻研究。本项目依托优化后的图形处理器（Graphics Processing Unit, GPU）代码与超级计算资源开展探测，可实现实时发现成果。在平方公里阵列望远镜（Square Kilometre Array, SKA）第一阶段的运行框架下，对实时流入的数据进行处理是核心需求，因此本项工作可直接适配下一代望远镜的高数据率观测场景。本项目发现的脉冲星多为邻近闪烁源、间歇辐射源，或是处于具有重要科学价值的双星系统中。本项目探测到的快速射电暴的响应延迟仅约1秒，而非传统流程所需的数月乃至数年；我们将通过专用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警报。该流程的核心目标是实现已发现快速射电暴的精准定位，这对于识别其宿主星系、解开其起源之谜，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。
