An axisymmetric hydrodynamical model for the torus wind in AGN. III: Spectra from 3D radiation transfer calculations
摘要：
我们计算了一系列的合成X射线光谱的流出源的模糊环在活动星系核（AGN）。这种建模包括X射线激发的环面风的2.5D流体动力学模拟，包括X射线加热，电离和辐射压力的影响。三维辐射传输计算在三维Sobolev近似中进行。合成的X射线谱和几个强线的个人档案显示在不同的倾角，观测时间，并为不同的特点的环面。我们的计算表明，丰富的合成温暖的吸收光谱从3D建模通常观察到在一个更大的范围内的倾斜比以前推断从简单的分析透射光谱。在一般情况下，我们的研究结果是支持温暖的吸收模型的基础上假设的“X射线激发漏斗流”，并与这些流的特征推断从塞弗特1星系的温暖的吸收观测是一致的。
英文摘要：
We calculate a series of synthetic X-ray spectra from outflows originating from the obscuring torus in active galactic nuclei (AGN). Such modeling includes 2.5D hydrodynamical simulations of an X-ray excited torus wind, including the effects of X-ray heating, ionization, and radiation pressure. 3D radiation transfer calculations are performed in the 3D Sobolev approximation. Synthetic X-ray line spectra and individual profiles of several strong lines are shown at different inclination angles, observing times, and for different characteristics of the torus. Our calculations show that rich synthetic warm absorber spectra from 3D modeling are typically observed at a larger range of inclinations than was previously inferred from simple analysis of the transmitted spectra. In general, our results are supportive of warm absorber models based on the hypothesis of an "X-ray excited funnel flow" and are consistent with characteristics of such flows inferred from observations of warm absorbers from Seyfert 1 galaxies.
