星系间的相互作用被认为是活动星系核（AGN）的一种机制。理论模型表明，相互作用是将气体从星系驱动到星系核的有效方式，然而，关于这个问题的观测证据是有争议的。在这里，我们回顾在这一领域的成果，讨论可能的局限性，以前的研究和处理选择效应的重要性。我们还发现，活动星系核中低光度星系和正常星系的伴星系所占的比例没有显著差异，并讨论了对这一结果的可能解释。http://adsabs.harvard.edu/abstract_service.html
Interactions between galaxies are suggested to be a mechanism responsible for feeding Active Galactic Nuclei (AGN). Theoretical models show that interactions are an efficient way to drive gas from the galaxy to the nucleus, however, the observational evidence on this subject is controversial. Here we review results in this field, discuss possible limitations of previous studies and the importance of dealing with selection effects. We also show that there is no significant difference in the percentage of low luminosity AGN and normal galaxies with companions, and discuss possible interpretations of this result.To search for other articles by the author(s) go to: http://adsabs.harvard.edu/abstract_service.html
