Parkes observations for project P892 semester 2018APRS_BPSR_08

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，开展脉冲星（pulsar）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）代码与超级计算机开展搜寻，可实现实时探测发现。在平方公里阵列射电望远镜（Square Kilometre Array, SKA）第一阶段的运行场景中，实时处理流式数据是核心要求，因此本研究的工作可直接适配下一代望远镜的高数据率处理需求。我们所发现的脉冲星，多为邻近的闪烁辐射源、间歇性辐射源，以及处于特殊双星系统中的天体。本次快速射电暴探测的延迟仅约1秒，而非传统流程所需的数月乃至数年，并通过专用VOEvent格式与《天文电报》（Astronomer's Telegrams）向全球后续观测社群快速发布预警信息。该工作的核心目标是实现已探测快速射电暴的精确定位，这对确定其宿主星系、解开其起源之谜，以及将其作为精密宇宙学测量工具以充分发挥多方面应用价值均具有关键意义。
