Distant galaxies in "AXAF Deep Field"

This image is a combination of a K-band image from ANTU/ISAAC with two images obtained in the B and R bands with the SUSI-2 optical imager at the New Technology Telescope (NTT) on La Silla. Note the relatively high density of red galaxies, visible in the upper right part of this image. The colours of most of these galaxies are consistent with those of "evolved" galaxies, already present when the Universe was only 4 billions years old.

The redshift, estimated on the basis of the measured colours of the mentioned over-density of yellow galaxies, is between 0.6 and 0.7 and that of the red galaxies is between 1 and 1.4.
