论文摘要
快速无线电爆发（FRB）是大约毫秒持续时间的明亮神秘的无线电脉冲，来自乳腺外距离。作为Meertrap项目的一部分，我们使用南非的Meerkat望远镜阵列来实时搜索并将这些爆发定位到很高的精度。我们的目标是将FRB指定到其宿主星系，从而了解它们的创建方式。但是，FRB的瞬态性质提出了各种挑战，例如在系统设计，原始计算功率和实时通信中，实时要求相当严格（几十秒）。快速数据处理对于我们来说，能够保留爆发的高分辨率数据，将其定位，并最大程度地减少随访观察的延迟至关重要。我们简要概述了数据分析管道，描述所面临的挑战，并详细介绍了我们在Meerkat望远镜上针对FRB的实时触发基础架构的初始设计和实施。
Fast Radio Bursts (FRBs) are bright enigmatic radio pulses of roughly millisecond duration that come from extragalactic distances. As part of the MeerTRAP project, we use the MeerKAT telescope array in South Africa to search for and localise those bursts to high precision in real-time. We aim to pinpoint FRBs to their host galaxies and, thereby, to understand how they are created. However, the transient nature of FRBs presents various challenges, e.g. in system design, raw compute power and real-time communication, where the real-time requirements are reasonably strict (a few tens of seconds). Rapid data processing is essential for us to be able to retain high-resolution data of the bursts, to localise them, and to minimise the delay for follow-up observations. We give a short overview of the data analysis pipeline, describe the challenges faced, and elaborate on our initial design and implementation of a real-time triggering infrastructure for FRBs at the MeerKAT telescope.
