活动星系核中的辐射驱动外流

Radiation-Driven Outflows in Active Galactic Nuclei

Daniel Proga, Ryuichi Kurosawa

摘要:

我们回顾了活动星系核气体动力学的多维含时模拟结果。我们将重点讨论两种由活动星系核中心引擎辐射驱动的外流:(1)来自吸积盘最内部的外流;(2)来自大规模流入的外流,它可能是中心引擎的主要物质供应者。我们讨论了这两种类型的外流的相关性,所谓的活动星系核反馈问题。然而,活动星系核的反馈不应该从活动星系核物理中分离出来单独考虑。因此,我们还讨论了这个问题是否相同的流出物的性质是一致的气体性质在宽和窄线区域。

英文摘要:

We review the results from multi-dimensional, time-dependent simulations of gas dynamics in AGN. We will focus on two types of outflows powered by radiation emitted from the AGN central engine: (i) outflows driven from the innermost part of an accretion disk and (2) outflows driven from a large-scale inflow that is likely the main supplier of material to the central engine. We discuss the relevance of both types of outflows to the so-called AGN feedback problem. However, the AGN feedback should not be considered separately from the AGN physics. Therefore, we also discuss the issue whether the properties of the same outflows are consistent with the gas properties in broad- and narrow-line regions.
