Properties of the galaxies hosting the MBHBs sourcing the CGWs detected by 30 year SKA: Galaxy stellar mass (M_*, upper left), sSFR (upper right), bulge-to-total ratio (B/T, lower left), and stellar magnitude in the (u, g, r, i, z) set of filters (lower right). In the panel with the sSFR, the vertical line highlights the 10⁻¹¹ yr⁻¹ value. On the other hand, the blue line corresponds to the cumulative distribution. Finally, the vertical lines correspond to the magnitude limits of LSST in the u, g, r, i, z filters.
