Influences of galaxy interactions on AGN activity
  Using two volume-limited Main galaxy samples of the Sloan Digital Sky Survey
Data Release 7 (SDSS DR7), we explore influences of galaxy interactions on AGN
activity. It is found that in the faint volume-limited sample, paired galaxies
have a slightly higher AGN fraction than isolated galaxies, whereas in the
luminous volume-limited sample, an opposite trend can be observed. The
significance is <1 sigma. Thus, we do not observe strong evidence that
interactions or mergers likely trigger the AGN activity.
