  2. Fluctuations down to 5x10-17 ergs/s/cm2 CDFS: extended sources

  3. CDFS vs COSMOS CDFS: extended sources

  4. Kirk structure at z=1.6 CDFS: extended sources

  5. Random catalog CDFS: extended sources

  6. Reproducing the observed emission CDFS: extended sources

  7. Simulated point sources CDFS: extended sources

  8. ACF of galaxy groups b_obs/b_model=1.1±0.1 This constraints the deviations from the assumed scaling relation to be < 30% in total mass. CDFS: extended sources

  9. GEMS CDFS: extended sources

  10. Lx-Mass from weak lensing lgM=0.6lgLx+C Ami Choi CDFS: extended sources

  11. Groups vs LCDM Finoguenov et al. 2010 CDFS: extended sources

  12. dn/dz – the void is 0.3<z<0.6 CDFS: extended sources

  13. Conclusions • ECDF-S delivered a very unique catalog of galaxy groups, probing interestingly low halo masses. • We have compared the mass calibration with the weak lensing signal and the clustering, finding a good agreement • Planck13 LCDM overpredicts the number of groups that should be visible in ECDF-S. Ths can be alleviated by ascribing 30% higher mass to each group. • Finally, the known lack of structure in CDFS is contained to 0.2<z<0.6 range. CDFS: extended sources

  14.
