Fig. 10.
Left panel: KDC relative size rKDC/reff versus the total merger gas fraction for 81 KDCs with associated mergers. Right panel: KDC relative size versus the total gas fraction at the time of the KDC births for all 134 KDCs. In both panels, the look-back time of the KDC birth is color coded and, for the KDCs with associated mergers, the circle sizes are proportional to the merger stellar-mass ratio. KDCs without associated mergers are represented by the square symbols.
