AGN流出反馈:可变性约束

AGN outflow feedback: Constraints from variability

R. G. Detmers, J. S. Kaastra

摘要:

我们提出了一个概述如何可变性可以用来约束附近的活动星系核使用高分辨率X射线光谱电离外流的位置。如果没有这些对流出位置的限制,就不能确定动力学光度和质量损失率。我们专注于塞弗特1星系NGC 5548,这可以说是最好的研究AGN的时间尺度为10年。我们的研究结果表明,频繁的观测与长期监测相结合,如与\textit{Rossi X-ray Timing Explorer (RXTE)}卫星,是至关重要的,以调查这些外流对其周围环境的影响。

英文摘要:

We present an overview on how variability can be used to constrain the location of the ionized outflow in nearby Active Galactic Nuclei using high-resolution X-ray spectroscopy. Without these constraints on the location of the outflow, the kinetic luminosity and mass loss rate can not be determined. We focus on the Seyfert 1 galaxy NGC 5548, which is arguably the best studied AGN on a timescale of 10 years. Our results show that frequent observations combined with long term monitoring, such as with the \textit{Rossi X-ray Timing Explorer (RXTE)} satellite, are crucial to investigate the effects of these outflows on their surroundings.
