Query: Morphology and Redshifts of Extremely Red Galaxies in the GOODS/CDFS
  deep ISAAC field   We present the photometric redshift distribution of a sample of 198 Extremely
Red Galaxies (ERGs) with Ks<22 and I-Ks>3.92 (Vega), selected by Roche et al.
in 50.4 sq. arcmin of the Chandra Deep Field South (CDFS). The sample has been
obtained using ISAAC-VLT and ACS-HST GOODS public data. We also show the
results of a morphological study of the 72 brightest ERGs in the z band (z<25,
AB).
