Spectral energy distributions for galaxies in high-redshift clusters - II. 0016+16at Z = 0.54.
Abstract
The authors have imaged the distant cluster 0016+16 (z = 0.54) through six intermediate-bandwidth filters ranging in wavelength from 418 to 862 nm, maintaining a photometric precision of 10 per cent to a limiting magnitude of F = 22. They find the field-subtracted colour distributions are not compatible with a single uniformly red population of early-type members at z = 0.54. They demonstrate how their six-colour data can be used to individually classify the galaxies by type and approximate redshift and thus they can identify which objects are members of the z = 0.54 cluster. On this basis they determine that the richness of the cluster is comparable to that of the Coma cluster.
