下一代康普顿望远镜和配对望远镜将 MeV 波段探测灵敏度比当前仪器能力提高十多年，将为各种天体物理源类别开辟新的见解。其中包括磁星，它是中子星动物园中磁性最强的一颗，它将成为新的兆电子伏窗口观测任务的主要科学目标。本文概述了此类技术可以解决的与磁星相关的核心问题。这些范围从全球磁星几何和人口趋势，到硬X射线发射地点的深入探测，再到为QED的奇异预测（主要是光子分裂和磁对产生的预测）提供光谱和偏振测试的宇宙实验室。这种基础物理学在地面实验中还无法被识别。提出了磁星中持久硬 X 射线尾发射的最先进模型，概述了使用康普顿旋光计进行强大诊断的案例。该案例凸显了在天文学和物理学之间的交叉领域播种发现的跨学科机会。
A next generation of Compton and pair telescopes that improve MeV-band detection sensitivity by more than a decade beyond current instrumental capabilities will open up new insights into a variety of astrophysical source classes. Among these are magnetars, the most highly magnetic of the neutron star zoo, which will serve as a prime science target for a new mission surveying the MeV window. This paper outlines the core questions pertaining to magnetars that can be addressed by such a technology. These range from global magnetar geometry and population trends, to incisive probes of hard X-ray emission locales, to providing cosmic laboratories for spectral and polarimetric testing of exotic predictions of QED, principally the prediction of the splitting of photons and magnetic pair creation. Such fundamental physics cannot yet be discerned in terrestrial experiments. State of the art modeling of the persistent hard X-ray tail emission in magnetars is presented to outline the case for powerful diagnostics using Compton polarimeters. The case highlights an inter-disciplinary opportunity to seed discovery at the interface between astronomy and physics.
