Narrow Band Photometry and the Evolution of Galaxies
Abstract
A direct comparison is conducted between the narrow-band colors of elliptical galaxies in distant clusters and the predictions of such spectral-evolution models as those of Bruzual (1983) and Guideronni and Rocca-Volmerange (1987). The photometric system used imitates the Stromgren passbands at the redshift of the clusters of galaxies in question. The colors of galaxies obtained at z lower than 0.3 are in agreement with such weakly evolving models as that of Bruzual, as well as with an open universe dominated by baryons whose mean density is approximately one-tenth the critical density.
