The model does not, however, explain how smaller galaxies such as our own have evolved to contain an SMBH at their centre.

但是这个模型并能解释较小的星系(比如银河系)是如何在其星系中心形成超大质量黑洞的。

The most likely cause for the black hole?s position off center is a previous merger between two older, smaller supermassive black holes (SMBH).

导致黑洞位置偏离中心的最可能的原因是原本的两个较小的特大质量黑洞的合并。
