Resumen:
We present here an investigation of the structure and dynamics of the superclusterSC0028-0005 at redshift 0.22. We have identified 6 members and used them to probe thesupercluster dynamics based on the hypothesis of spherical collapse in a ΛCDM Universe.The inner region, inside 10 Mpc, has a mass between 4 and 16 × 1015M. Consideringthe outer region, within 60 Mpc, the mean density is about 3 times the Universe criticaldensity at the supercluster redshift.
