Parkes observations for project P892 semester 2018APRS_BPSR_49

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项目瞄准银纬极高的天区，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GPU运算代码与超级计算集群开展搜寻，可实现实时发现。在平方公里阵列（Square Kilometre Array, SKA）一期时代，实时处理流式数据是核心需求，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场景。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脉冲星。本项目发现快速射电暴的发现时延仅约1秒，远快于传统的数月乃至数年的周期；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推送预警信息。此举的核心目标是实现已发现快速射电暴的精确定位，这对于识别快速射电暴的宿主星系、揭开其起源之谜，以及将其作为精密宇宙学测量工具发挥多重应用价值均至关重要。
