SMBH locations within disk galaxies. The distribution of polar angles relative to halo center and the the plane of the galactic disk for wandering SMBHs (0.7 < D < 10 kpc) in MW-mass disk galaxies from ROMULUS25 (blue line). The dashed black line represents the expectation from randomly sampling a unit sphere. In ROMULUS25, wandering SMBHs show a clear preference to exist out of the disk plane.
