M_BH/M_* as a function of redshift. Stacks with detected broad Hα emission are shown with red filled stars, and 3σ BH mass upper limits are shown with red open stars. Other JWST-detected BLAGN are shown: H. Übler et al. (2023, plus), Y. Harikane et al. (2023, circles), R. Maiolino et al. (2024a, diamonds), and D. D. Kocevski et al. (2023, crosses). Another stacking analysis, performed by S. Geris et al. (2026) in the JADES deep fields, is shown with triangles. The mean of the local AGN population (A. E. Reines & M. Volonteri 2015) is shown with a filled gray square. A high-z (z  >  4) scaling relation from F. Pacucci & A. Loeb (2024) is shown with the dashed black line.
