BH mass as a function of host galaxy properties, specifically: Stellar mass (top left), velocity dispersion (bottom left), and dynamical mass (bottom right). The JADES results presented in this work are shown with large golden circles. Dashed orange vertical lines connect candidate merging BHs. Blue symbols indicate measurements from other JWST surveys at high-z, as is indicated in the legend (only detections at > 3σ are shown). Grey triangles are measurements of high-z QSOs using ALMA data. Small red symbols show the distribution of local galaxies, as is indicated in the legend; straight lines show the local relation fits (with shaded regions providing the scatter and slope uncertainty), using the samples that are best matching our high-z systems, in each panel (see text for details). In the top left panel, small orange circles show the maximum stellar masses estimated for a few JADES AGNs (see text) and the dotted violet lines show constant values of the M_BH/M_star ratio. In the bottom left panel, small squares indicate the effect of correcting for rotation velocity broadening within the slit.
