AI 中文总结
该研究提出用H₂发射线作新型诊断识别矮星系活动星系核，通过光致电离模型及WISE模板进行判断。虽H₂ 2.12μm/Brγ比值有局限，但特定条件下H₂发射线比值可揭示活跃中等质量黑洞，有望探测最难捉摸的此类黑洞。
AI 中文摘要
我们提出通过运行包含活跃中等质量黑洞的光致电离模型，并以观测到的WISE矮星系活动星系核为模板，使用H₂发射线作为一种新型诊断方法来识别矮星系活动星系核。虽然若使用H₂ 2.12μm/Brγ比值，许多矮星系活动星系核会被误分类为恒星形成星系，但在log $n_{\text{H}} \gtrsim 4.0$的情况下，H₂发射线之间的比值可揭示活跃的中等质量黑洞。这包括$M_{\text{BH}} = 10^3~M_{\odot}$的情况，即便光学强线和近红外冕线可能未被探测到。我们得出结论，H₂发射线在探测最难以捉摸的中等质量黑洞方面显示出前景。
英文摘要
We propose using H$_{2}$ emission lines as a novel diagnostic to identify dwarf AGN by running photoionization models incorporating active intermediate-mass black holes and using an observed WISE dwarf AGN as a template. Though many dwarf AGN would be incorrectly classified as star-forming if the H$_{2}$~2.12~$μ$m/Br$γ$ ratio is used, ratios between H$_{2}$ emission lines can reveal active IMBHs in cases where log $n_{\text{H}} \gtrsim 4.0$. This includes the case where $M_{\text{BH}} = 10^3~M_{\odot}$, even though the optical strong lines and NIR coronal lines would likely go undetected. We conclude that H$_{2}$ emission lines show promise in detecting the most elusive IMBHs.
