Parkes observations for project P1154 semester 2022APRS_06

Pulsars with high surface magnetic field-strengths (high-B pulsars) provide a rich seam of study for both observers and theorists alike. Studies of their population properties have the potential to answer several fundamental questions about the nature of these objects and how they fit in with the overall pulsar population. These questions include: How do their magnetic fields arise? How is pulsed radio emission produced above the quantum critical field? How do the various populations of high-B pulsars evolve with time? In this proposal we will use the Ultra-Wideband Low (UWL) receiver system on Parkes to complete a Southern-Sky radio census of these high-B pulsars in order to determine their geometric and emission properties with the aim of providing the answers to the questions posed above.

高表面磁场强度脉冲星（high-B pulsars）为观测研究者与理论研究者均提供了丰富的研究课题。针对其种群特性的研究，有望解答一系列关于这类天体本质，以及它们如何融入整体脉冲星种群的核心问题。这些问题包括：其磁场如何起源？脉冲射电辐射如何在量子临界磁场之上产生？各类高表面磁场强度脉冲星种群如何随时间演化？在本研究提案中，我们将利用帕克斯（Parkes）望远镜搭载的超宽带低频（Ultra-Wideband Low，UWL）接收系统，完成针对南天区高表面磁场强度脉冲星的射电巡天普查，以明确其几何特性与辐射属性，进而为解答上述核心问题提供支撑。
