Fig. 4


Mass-radius relation for the high-density cores in the supercluster SCl 027. Violet line shows embedded mass M versus radius of a sphere R for the turnaround T, and dashed grey line for the future collapse FC. The red line shows embedded mass versus radius for the region around the cluster A1650, the blue line shows the region around the cluster A1750, and the green line the region around the cluster A1773.
