Radial density profiles of the galaxies from the three ROMULUS25 SMBH triple systems A (left column), B (middle column), C (right column). The solid lines show the actual ROMULUS25 data, while the dashed lines show fits with Hernquist and Dehnen models. Dark matter is color-coded purple, stars red, and gas green. The alternative stellar density fits for the initial conditions A.2 and A.3 are shown as dashed orange and pink lines respectively. Galaxy 3 in system A did not contain any gas. As stated, in system A the three SMBHs were hosted by three different galaxies, in system B by just two, and in system C by just one. The gray shaded areas were excluded from the fit, the dotted lines in the diagrams for the primary galaxies (top row) show the distance of BH2 and BH3 from their centers, where the heaviest black hole, i.e. BH1, of each triple system resides.
