Environment effect on the integrated mass functions. All samples have been split in two, as stated by the legend, with the terms “Over”and “Under”referring to high-density environments (over the median value) and low-density ones (under the median value). Upper panel: red and purple triangles refer to quiescent UltraVISTA galaxies, cyan and blue squares to the AGN sample. Lower panel: black and grey curves represent the ratio of AGN hosting to quiescent galaxies. Solid lines are for high-density environments, dashed lines for the low-density ones. Points have been placed at values of redshift corresponding to the mean redshift of each redshift bin.
