Scientific paper

Near-infrared photometry for 61 elliptical galaxies is used with previously published data to demonstrate that little or no color evolution is observed at infrared wavelengths, while galaxies near z = 1 are brighter than those at low redshift. Optically selected galaxies are compared with radio galaxies, and no differences in infrared properties are found. Evolution of a stellar population with an initial mass function similar to that observed in the solar neighborhood coupled with a value for q0 near 0.5 provides the best fit to the color and luminosity data.
