Scientific paper

Simple 'no evolution' predictions are supported by new spectroscopic observations of a statistically complete sample of 50 very faint I-band selected galaxies, despite a roughly threefold excess in the number-magnitude counts relative to a no-evolution q(0) = 0.5 model. This points to a domination of the faint field galaxy population by a rapidly evolving population of numerous, and presumably relatively low-mass galaxies. Nevertheless, a Lambda-dominated universe with q(0) of about -0.85 would require little evolution in the luminosity function at rest wavelengths of about 5500 A back to z of about 0.5
