在本文中，我们提出了一种有趣的方法来检验活动星系核(AGN)的双超质量黑洞模型，该模型具有双峰窄[OIII]谱线(双峰窄发射体)，通过宽的光学巴尔默线性质。在双峰窄发射体的对偶超大质量黑洞模型下，由观测到的广义Balmer线性质估计的维里黑洞质量可能比真正的黑洞质量(中心两个黑洞的总质量)要小。然后，我们比较了37个具有宽巴尔默线的双峰窄辐射源和斯隆数字天空测量中心选取的具有单峰的正常宽线活动星系核的维里黑洞质量。然而，我们可以发现37条宽线活动星系核在统计上比正常的宽线活动星系核要大得多。因此，我们得出的结论是，双超质量黑洞模型在统计学上可能并不比双峰窄发射体模型更好，需要更多的努力来仔细地根据观测到的双峰窄发射线来寻找双超质量黑洞的候选者。
In this paper, we proposed an interesting method to test the dual supermassive black hole model for active galactic nucleus (AGN) with double-peaked narrow [Oiii] lines (double-peaked narrow emitters) through their broad optical Balmer line properties. Under the dual supermassive black hole model for double-peaked narrow emitters, we could expect statistically smaller virial black hole masses estimated by observed broad Balmer line properties than true black hole masses (total masses of central two black holes). Then, we compare the virial black hole masses between a sample of 37 double-peaked narrow emitters with broad Balmer lines and samples of Sloan Digital Sky Survey selected normal broad line AGN with single-peaked [Oiii] lines. However, we can find clearly statistically larger calculated virial black hole masses for the 37 broad line AGN with double-peaked [Oiii] lines than for samples of normal broad line AGN. Therefore, we give our conclusion that the dual supermassive black hole model is probably not statistically preferred to the double-peaked narrow emitters, and more efforts should be necessary to carefully find candidates for dual supermassive black holes by observed double-peaked narrow emission lines.
