论文摘要
最近的ALMA观察结果在最近的SY2 Galaxy，NGC1068中，在毫米频段中解决了遮盖的圆环。这些观察结果已经证实了具有轨道运动及其物质的轨道运动及其速度分布的几何厚的圆环的存在，这可以反映块状结构。在N体模拟的框架中，我们考虑了一个模糊的圆环的动力学模型，该模型解释了中央质量场中移动的云之间的重力相互作用。在被考虑的模型中，云在中央质量周围绕着倾斜度和偏心率展现出来。圆环的自我重力通过全球轨道运动诱导云的速度分布，该运动模仿了NGC1068的Alma数据。
Recent ALMA observations have resolved the obscuring torus in the nearest Sy2 galaxy, NGC1068, in the millimeter band. These observations have confirmed the presence of a geometrically thick torus with an orbital motion of its matter and the velocity distribution which can reflect the clumpy structure. In the framework of N-body simulations we consider a dynamical model of an obscuring torus which accounts for the gravitational interaction between the clouds moving in the field of the central mass. In considered model, clouds are orbiting around the central mass exhibiting a spread in inclination and eccentricity. The self-gravity of the torus induces the velocity distribution of clouds with a global orbital motion which mimics the ALMA data for NGC1068.
