Diagnostic diagrams for EELGs. Large symbols indicate purely star-forming systems (colored) and AGN candidates (black). Small gray dots show galaxies from the SFG-20k parent sample. Colors are as in Fig. 3 and labels indicate the redshift of each subset of galaxies. AGN candidates include both galaxies with detected X-ray counterparts (squares) and galaxies with broad Balmer line components and/or high-ionization emission lines (triangles). Lines show the empirical separation between SFGs and AGNs.
