A Possible Evolutionary Connection between AGN and Starburst in LINERs

摘要: Our analysis on the two magnitude-limited samples of LINERs suggests a correlation between $L_{\FIR}/L_{\B}$ or f(25\micron)/f(60\micron), and Hubble-type index at $>$99.99% significance level. As f(25\micron)/f(60\micron) are considered as indicators star-formation activity AGN activity, respectively, our result that with higher may have lower contribution. The ones highest lowest contributions ellipticals. All well-studied LINER 1s belong to this group. On other hand, present contributions. We find all 2s in parameter space. Most having inner ring structures Statistics (nulear mass-to-light ratio H band, X-ray-to-UV power) provide further evidence for such trend. seen along evolution galaxies from late-type spirals early-type ones, up ellipticals, intensity increases decreasing contributions, above analyses suggest possible connection host nuclear activities, it might also indicate evolutionary starburst LINERs.
