Im simulations

Myungshim Im & Peter Stockman (STScI) have simulated deep NGST images in the I (0.8 micron), J (1.2 micron) and K (2.0 micron) with a bandwidth ratio of 0.5. The telescope was assumed to have an 8m class mirror, exposure time was 10 hours per passband. Only 2'x2' of the proposed 4'x4' NIRCam field of view was modeled.

They used traditional passive evolution to model the appearance of galaxies from z=0 to z=5 and used a Press-Schecter formula to model the light of star forming proto-galaxies between z = 5 to z = 20 a la Haimon and Loeb (1996). The Hubble constant used was 65km/s/Mpc and Omega=0.3 (i.e. open CDM cosmology).

A 24"x24" simulated NGST image labeled with redshifts. The image has 0.06 arcsecond resolution in all three bands (i.e. diffraction-limited at 2 microns). This represents only 1% of the total NIRCam field of view. This image is also available in a postscript version (3.7 Mb).

We have also images of the full 2'x2' image simulation in 900x900 pixels compressed JPEG format (153 kb) and full 4096x4096 resolution gzipped TIFF format (40 Mb).

We have a page with more detailed descriptions and more images (NGST and ground based images, with and without redshifts).
