Parkes observations for project P1154 semester 2022APRS_07

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.

具有高表面磁场强度的脉冲星（high-B pulsars）为观测研究与理论探索均提供了丰富的研究资源。针对这类天体的种群特性开展研究，有望解答诸多有关其本质，以及它们如何融入整体脉冲星种群的基础性问题。这些问题包括：其磁场的起源机制是什么？量子临界场之上的脉冲射电辐射是如何产生的？各类高表面磁场强度脉冲星种群随时间的演化规律为何？在本研究计划中，我们将利用帕克斯（Parkes）望远镜的超宽带低频（Ultra-Wideband Low, UWL）接收系统，完成针对南天区域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特性，旨在为上述问题提供解答。
