论文摘要
事件地平线望远镜(EHT)发布了对M87 Galaxy中心的超质量黑洞附近地平线毫米发射的重建图像的分析。分析的一部分利用了大型合成黑洞图像和光谱的库,这些图像是使用数值一般相对论磁性流体动力学模拟和偏振光射线跟踪产生的。在本文中,我们描述了Patoka管道,该管道用于为EHT模拟库产生伊利诺伊州的贡献。我们首先要描述相关的增生系统和辐射过程。然后,我们描述使用IHARM,IPOLE和IGRMOMTY使用的三个数值代码的细节,特别注意当前代码和最初发布的版本之间的差异。最后,我们简要概述了Patoka产生的模拟数据,并以讨论局限性和未来方向的讨论。
The Event Horizon Telescope (EHT) has released analyses of reconstructed images of horizon-scale millimeter emission near the supermassive black hole at the center of the M87 galaxy. Parts of the analyses made use of a large library of synthetic black hole images and spectra, which were produced using numerical general relativistic magnetohydrodynamics fluid simulations and polarized ray tracing. In this article, we describe the PATOKA pipeline, which was used to generate the Illinois contribution to the EHT simulation library. We begin by describing the relevant accretion systems and radiative processes. We then describe the details of the three numerical codes we use, iharm, ipole, and igrmonty, paying particular attention to differences between the current generation of the codes and the originally published versions. Finally, we provide a brief overview of simulated data as produced by PATOKA and conclude with a discussion of limitations and future directions.
