Simulated NGST Observations
  This paper presents the results of simulated NGST observations. The goal of this work is to study the detectability of very high redshift galaxies and to try to characterize Wide Deep-Field observations. The main points made in this paper are 1) high-z galaxies observable by NGST would be similar to local starburst galaxies 2) even if they exist, large spiral galaxies similar to local ones would not be observed by a NGST-like telescope and 3) the density of high-z galaxies detected so far is apparently moderate.
