Numerical simulations of hierarchical galaxy formation, including gasdynamics, star formation, and supernova feedback, are presented. The simulations model the collapse of isolated constant-density perturbations, initially in solid-body rotation and in Hubble flow. A three-component system that resembles a spiral galaxy - a thin disk made of stars and gas, a spheroidal component consisting of stars, and a dark matter halo - is made. The star formation history is combined with population synthesis models to determine the absolute and apparent brightness of the simulated galaxy in many color bands. Simulated observations are also made. The system is brightest during a burst of star formation that occurs as the disk forms. It first reaches its peak I-magnitude of 22 at z of 2 and is fainter than B of 4.5 at z of 1.
