我们提出了活动星系核(AGN)窄线区(NLR)的中红外和远红外辐射模型。利用Mappings III程序，研究了典型的NLR参数对红外发射光谱特性的影响。其中包括用于确定这些参数的有用的红外发射线比诊断图，以及恒星形成和活动星系核混合诊断。我们还检查了发射线与连续谱的相关性，这将有助于分离来自NLR的IR发射和来自内环的IR发射。我们发现，对于像NGC1068和NGC4151这样的活动星系核，NLR只贡献了∼总IRAS 25微米通量的10%，而其他组件，如尘土飞扬的环状结构，是解释活动星系核总红外发射所必需的。
We present models for the mid- and far- infrared emission from the Narrow Line Region (NLR) of Active Galactic Nuclei (AGN). Using the MAPPINGS iii code we explore the effect of typical NLR parameters on the spectral characteristics of the IR emission. These include useful IR emission line ratio diagnostic diagrams for the determination of these parameters, as well as Star formationAGN mixing diagnostics. We also examine emission line to continuum correlations which would assist in separating the IR emission arising from the NLR from that coming from the inner torus. We find for AGN like NGC 1068 and NGC 4151 that the NLR only contributes ∼10% to the total IRAS 25 µm flux, and that other components such as a dusty torus are necessary to explain the total AGN IR emission.
