Parkes observations for project P892 semester 2018APRS_BPSR_01

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聚焦银道坐标系最高银纬区域，开展脉冲星（pulsars）与快速射电暴（fast radio bursts, FRBs）的搜寻工作。本研究采用优化后的图形处理器（GPU）代码与超级计算资源进行搜寻，可实现实时发现。在平方公里阵列（Square Kilometre Array, SKA）一期阶段，实时处理传入数据至关重要，因此本项工作可直接适配下一代望远镜的高数据率场景。

我们发现的脉冲星通常为邻近闪烁源、间歇源，以及处于具有研究价值的双星系统中的脉冲星。本项目发现快速射电暴的延迟仅约1秒，而非数月乃至数年，并通过专用VOEvent格式与《天文学家电报》（Astronomer's Telegrams）向全球后续观测社群快速发布警报，以此实现已发现快速射电暴的定位。这一能力是识别快速射电暴宿主星系的关键，进而可破解其起源前身天体的谜团，并将其作为高精度宇宙学测量工具加以利用。
