AGN-related dust-corrected Hβ luminosities and detection thresholds for MaNGA galaxies, as a function of various host galaxy properties: stellar mass (top left), stellar velocity dispersion σ_e (top right), SFR (bottom left), and sSFR (bottom right). The red points show detections. The vast majority (∼97%) of galaxies do not have detections and yield only luminosity thresholds. The gray scale shows the cumulative conditional distribution of these thresholds. That is, for each value of each host galaxy property, it shows the fraction of galaxies for which any given luminosity would be detectable. For example, at low SFR, an AGN with L(Hβ)_corr ∼ 10⁴⁰ erg s⁻¹ would be detectable for 90% of galaxies, but at high SFR the same AGN would be detectable only for 10% of galaxies.
