Properties of different spectral types of AGN as a function of density contrast. We can see that the stellar mass drops with the density due to gas stripping and high density objects show a stronger starburst and younger stellar populations. The line in C = 2.6 separates the early- and late-type galaxies, showing that Seyferts and LINERs are found in early-type hosts. The left panels show that AGN properties are more dependent on the density than on the web-type.
