Parkes observations for project P892 semester 2018APRS_BPSR_24

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，开展脉冲星与快速射电暴（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）代码与超级计算资源开展搜寻，可实时完成探测发现。对于平方公里阵列（Square Kilometre Array, SKA）第一阶段的运行需求而言，实时处理实时传入的观测数据至关重要，因此本项目的技术方案可直接适配下一代望远镜的高数据率场景。本项目发现的脉冲星多为邻近的闪烁源、间歇源，以及处于特殊双星系统中的天体。本项目发现快速射电暴的探测延迟仅约1秒，而非数月乃至数年；我们通过专用的虚拟观测事件（Virtual Observatory Event, 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预警信息。本项目的核心目标是实现已探测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前提，进而得以破解其起源天体的谜题，并充分利用其作为高精度宇宙学测量工具的多重应用价值。
