标题： Pseudo-3D visualization of Faraday structure in polarized radio sources: methods, science use cases, and development priorities

摘要： 我们介绍了极化强度立方体$P$(赤经 RA, 赤纬 Dec,$\Phi$) 的构建及其作为电影的可视化技术，这是一种解释法拉第结构的强大方法。 $P$是由峰值偏振强度 P(RA, Dec) 地图及其对应的法拉第深度地图$\Phi$(赤经 RA, 赤纬 Dec) 构建而成。 我们通过 ASKAP 和 MeerKAT 的各种科学应用实例展示了此类可视化的巨大科学潜力，并提出了与数据一致但不一定唯一的模型。 我们演示了原则上如何区分来自无关前景屏幕的立方体结构和源于发射源附近磁化等离子体的结构。 其他科学应用实例展示了如何利用法拉第旋转来区分本地$n_e$ $B$ 及到同步辐射发射区域的视线距离的变化。 我们首次展示了如何确定活动星系核 (AGN) 喷流的视线方向。 我们也研究了 M87 案例，展示了如何识别内部喷流磁场配置，并扩展了早期的结果。 我们建议使用此技术重新评估所有先前对空间上和法拉第深度上均清晰解析的偏振源的分析。 认识到这一早期阶段解释的主观性，我们也强调了进一步科学发展和技术发展的必要性和实用性。 显示英文摘要

摘要： We introduce the construction of polarized intensity cubes $P$(RA, Dec, $\Phi$) and their visualization as movies, as a powerful technique for interpreting Faraday structure. $P$ is constructed from maps of peak polarized intensity P(RA, Dec) with their corresponding Faraday depth maps $\Phi$(RA, Dec). We illustrate the extensive scientific potential of such visualizations with a variety of science use cases from ASKAP and MeerKAT, presenting models that are consistent with the data but not necessarily unique. We demonstrate how one can, in principle, distinguish between cube structures which originate from unrelated foreground screens from those due to magnetized plasmas local to the emitting source. Other science use cases illustrate how variations in the local $n_e$ $B$, and line-of-sight distance to the synchrotron emitting regions can be distinguished using Faraday rotation. We show, for the first time, how the line-of-sight orientation of AGN jets can be determined. We also examine the case of M87 to show how internal jet magnetic field configurations can be identified, and extend earlier results. We recommend using this technique to re-evaluate all previous analyses of polarized sources that are well-resolved both spatially and in Faraday depth. Recognizing the subjective nature of interpretations at this early stage, we also highlight the need and utility for further scientific and technical developments.
