MEx diagram for the sample of galaxies analyzed in this paper: black dots and green squares are for the GLASS-JWST and DDT samples, respectively. For reference, we plot also the galaxies at z = 0.3 − 0.4 from Flury et al. (2022) (diamonds) and the LCE candidates from previous studies (stars, Izotov et al. 2016a,b, 2018b,a, 2021; Wang et al. 2019). The two orange demarcation lines from Juneau et al. (2014) show the boundaries of the AGN-and-star-forming transition region. All objects above the upper line are AGN-dominated; all galaxies below or rightward of the lower line are presumptively dominated by star formation. We also show the separation from Coil et al. (2015) (dotted lines), which is the adaptation of the Juneau et al. model for galaxies and AGNs at z ∼ 2.3 from the MOSDEF survey.
