Parkes observations for project P892 semester 2018OCTS_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 聚焦于最高银纬天区，开展脉冲星与快速射电暴（fast radio bursts, FRBs）的搜索工作。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相关搜索，可实现实时发现成果。在平方公里阵列（Square Kilometre Array, SKA）第一阶段的运行框架下，实时处理传入数据是核心要求，因此本研究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响应时延仅约1秒，而非数月乃至数年；我们会通过专用的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，此举旨在实现已发现快速射电暴的精准定位。这对识别快速射电暴的宿主星系至关重要，进而得以破解其起源之谜，并将其作为精密宇宙学测量工具加以利用。
