Parkes observations for project P858 semester 2015APRS_BPSR_29

SUPERB is a large-scale survey for pulsars and extragalactic radio bursts. It will uses optimised GPU codes to search for pulsars and fast radio bursts (FRBs), 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. The pulsars discovered will enable studies of the interstellar medium, allow us to more accurately constrain the MSP luminosity function (which informs estimates of the SKA yield of MSPs), tests of theories of gravity and several will contribute to the precision timing projects of the PPTA. The FRBs discovered will have much more associated information than all previous detections. Firstly the discovery lag will be ~1 second, rather than months/years. The Parkes observations will be shadowed by the Molonglo telescope to allow, for the first time, localisation of FRBs, and a host of optical and high-energy telescopes will then be triggered as appropriate. This is key for identifying FRB host galaxies, so as to solve the mystery of their progenitors. The survey will discover ~20 MSPs, ~100 slower pulsars and ~10 FRBs.

SUPERB是一项面向脉冲星与河外射电暴的大规模巡天项目。该项目将采用优化后的图形处理器（Graphics Processing Unit, GPU）代码开展脉冲星与快速射电暴（Fast Radio Bursts, FRBs）的搜寻工作，实现实时发现新天体。在平方公里阵列（Square Kilometre Array, SKA）第一阶段的时代背景下，实时处理传入数据至关重要，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需求。本次巡天发现的脉冲星将可用于星际介质研究，帮助我们更精准地限定毫秒脉冲星（Millisecond Pulsar, MSP）的光度函数（该函数可为平方公里阵列的毫秒脉冲星产出率估算提供依据），同时可用于引力理论检验，其中部分脉冲星还将助力帕克斯脉冲星计时阵列（Parkes Pulsar Timing Array, PPTA）的高精度计时项目。本次发现的快速射电暴将拥有远超此前所有探测案例的关联信息：其一，发现延迟将仅约1秒，而非数月乃至数年。帕克斯（Parkes）望远镜的观测将由莫隆格洛（Molonglo）望远镜进行同步遮蔽，这将首次实现快速射电暴的定位；随后可根据需要触发大量光学与高能望远镜开展观测。这一技术对于确定快速射电暴的宿主星系至关重要，进而助力破解其起源天体的谜题。本次巡天将预计发现约20颗毫秒脉冲星、约100颗慢速脉冲星以及约10个快速射电暴。
