Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>We analyzed the spectra collected under the wide‐field nearby galaxy clusters survey (WINGS) to reveal emission lines in cluster galaxies. After removing stellar emission with dedicated population synthesis models we found evidence of faint emission line activity in a sizable number of sources. Diagnostic diagrams were used to define or at least constrain the origin of the emission line activity. Cross‐correlation with radio surveys is also being used for the identification of "true" active nuclei. We report the discovery of a previously unknown Seyfert 1 nucleus, WINGS J230945.81+072431.0, and preliminary results on prevalence and basic properties of the active and star forming galaxies we identified.
