类星体风模型

A Quasar Wind Model

Andrea Ruff

摘要:

提出了一个类星体风模型来描述宽线区的空间和速度结构。该模型需要详细的光电离和磁流体动力学模拟,因为宽线区域太小,无法直接进行空间分辨率。由于气体高速运动,发射谱线都卜勒展宽。气体通过辐射和磁驱动力的组合获得高速度。一旦这个模型完成,模型的预测将与最近的微透镜数据结合各种现有的观测进行测试。

英文摘要:

A quasar wind model is proposed to describe the spatial and velocity structure of the broad line region. This model requires detailed photoionization and magnetohydrodynamic simulation, as the broad line region it too small for direct spatial resolution. The emission lines are Doppler broadened, since the gas is moving at high velocity. The high velocity is attained by the gas from a combination of radiative and magnetic driving forces. Once this model is complete, the model predictions will be tested against recent microlensing data in conjunction with diverse existing observations.
