We present the results of a systematic, broadband X-ray spectral analysis of nearby active galactic nuclei (AGNs) with the X-ray clumpy torus model (XCLUMPY; Tanimoto et al. 2019). By adding 16 AGNs newly analyzed in this paper, we study total 28 AGNs including unabsorbed and absorbed AGNs taken from Ichikawa et al. (2015) and Garc\'ia-Bernete et al. (2019). This is the largest sample whose X-ray and infrared spectra are analyzed by the clumpy torus models XCLUMPY and CLUMPY (Nenkova et al. 2008), respectively. The relation between the Eddington ratio and the torus covering factor determined from the X-ray torus parameters of each object follows the trend found by Ricci et al. (2017) based on a statistical analysis. We confirm the results by Tanimoto et al. (2020) that (1) the torus angular widths determined by the infrared data are larger than those by the X-ray data and that (2) the ratios of the hydrogen column density to V-band extinction ($N_{\rm H}/A_{\rm V}$) along the line of sight in obscured AGNs are similar to the Galactic value on average. Unobscured AGNs show apparently smaller line-of-sight $N_{\rm H}/A_{\rm V}$ ratios than the Galactic one. Our findings can be well explained by an updated unified picture of AGN structure including a dusty torus, dusty polar outflows, and dust-free gas, where the inclination determines the X-ray and optical classifications and observed torus properties in the X-ray and infrared bands.

用宽带 X 射线光谱系统研究 AGN 块状环面：更新的 AGN 结构统一图

我们展示了使用 X 射线团块环面模型 (XCLUMPY; Tanimoto et al. 2019) 对附近活动星系核 (AGN) 进行系统的宽带 X 射线光谱分析的结果。通过添加本文新分析的 16 个 AGN，我们研究了总共 28 个 AGN，包括从 Ichikawa 等人那里获取的未吸收和吸收的 AGN。(2015) 和 Garc\'ia-Bernete 等人。(2019)。这是最大的样本，其 X 射线和红外光谱分别由块状环面模型 XCLUMPY 和 CLUMPY（Nenkova 等人，2008 年）进行分析。Eddington 比和由每个物体的 X 射线环面参数确定的环面覆盖因子之间的关系遵循 Ricci 等人发现的趋势。(2017) 基于统计分析。我们确认了 Tanimoto 等人的结果。(2020) (1) 由红外数据确定的环面角宽度大于由 X 射线数据确定的环角宽度和 (2) 氢柱密度与 V 带消光的比值 ($N_{\rm H }/A_{\rm V}$) 在被遮挡的 AGN 中沿视线的平均水平与银河值相似。无遮挡的 AGN 显示出明显比银河系更小的视线 $N_{\rm H}/A_{\rm V}$ 比率。我们的发现可以通过更新的 AGN 结构统一图片得到很好的解释，包括多尘环面、多尘极地流出和无尘气体，其中倾斜度决定了 X 射线和光学分类以及在 X 射线和红外波段。
