Fraction of central dwarf galaxies hosting AGNs according to different minimum thresholds for variables used in the sample selection. Top panel: AGN fraction as a function of the minimum threshold for λ_Edd. Bottom panel: AGN fraction as a function of the minimum threshold for stellar mass. In each panel, the solid lines show the fraction for different values of λ_Edd, min or M_*,min, with the shaded regions representing the 95% confidence intervals. The red dashed lines indicate the overall fraction of dwarf AGN candidates from the DESI survey (Pucha et al. 2025), for the whole mass range of 8 ≲ log(M_*/M_⊙)≤9.5. This value (∼1.2%) is derived from the values presented in their figure 7 (right panel), and is the fraction of dwarf galaxies identified as AGN/Composite in the [N II]–BPT diagram, over the total number of dwarf galaxies (including dwarf galaxies without emission lines).
