AI 中文摘要
本研究通过黑洞吸积与喷流启动的广义相对论辐射转移计算，重现亚秒差距尺度下M87喷流的观测特性。首次在模拟中于喷流启动区域加入团块组分，成功重现准同时性低能能谱分布（10^10 Hz ≤ ν ≤ 10^16 Hz）；同时在自吸收区域（ν ≤ 10^11 Hz）的同步辐射拟合效果更优，表明辐射转移计算中加入团块组分会产生更平缓的能谱（α_22-86 GHz=0.08）。此外，模拟提升了M87喷流观测形态的拟合精度，在86 GHz下可匹配至距核心0.6角秒的区域；所得合成图像可重现南部边缘的亮边结构至约1.3角秒，较以往研究覆盖范围更广，且南部边缘更亮，还能复现南部边缘的额外观测 knot。
英文摘要
In this work, we present results from general-relativistic radiative-transfer calculations of black hole accretion and jet launching to reproduce the observed properties of the M\,87 jet at sub-parsec scales. For the first time, in the simulations we have included a blob component at the launching region of the jet that allowed us to reproduce the quasi-simultaneous low-energy spectral energy distribution ($10^{10} \text{ Hz} \leq ν\leq 10^{16} \text{ Hz}$). Moreover, we obtain a better fit of the synchrotron emission in the self-absorption region ($ν\leq 10^{11} \text{ Hz}$), showing that the inclusion of a blob component in our radiative transfer calculations results in a flatter spectrum ($α_{22-86\ \text{GHz}}=0.08$). Additionally, our simulations improved the accuracy of the observed morphology of M\,87's jet, matching the data up to a distance of 0.6 mas from the core at 86 GHz. Our results reproduce the edge-brightened structure up to $\sim1.3$ mas, i.e., in a more extended region compared with previous studies, with a brighter southern edge. The obtained synthetic image of the jet reproduces additional observed knots along the southern edge.
