Abstract:

Simulations of a distant cluster of galaxies at z2 are presented for the HST cameras COSTAR-corrected FOC, WFPC II, the Advanced Camera, and for an adaptive optics system that may equip a future 8-meter class telescope. Except for the FOC and PC II, the faint objects are detected in 200 minutes, with identifiable morphological types. The Advanced Camera offers the biggest advantages due to its large field, great sensitivity, and high angular resolution.

Keywords: cluster of galaxies, simulations
