J/ApJ/241/486  Absolute magnitudes in 116 nearby Abell clusters (Hoessel+, 1980)

The photometry properties of brightest cluster galaxies. I. Absolute magnitudes in 116 nearby Abell clusters. Hoessel J.G., Gunn J.E., Thuan T.X. <Astrophys. J., 241, 486-492 (1980)> =1980ApJ...241..486H (SIMBAD/NED BibCode)
ADC_Keywords: Clusters, galaxy ; Magnitudes, absolute ; Redshifts Keywords: cosmology - galaxies: clusters of - galaxies: photometry - galaxies: structure Abstract: Two-color aperture photometry of the brightest galaxies in a complete sample of nearby Abeil clusters is presented. The results are used to anchor the bright end of the Hubble diagram; essentially the entire formal error for this method is then due to the sample of distant clusters used. New determinations of the systematic trend of galaxy absolute magnitude with the cluster properties of richness and Bautz-Morgan type are derived. When these new results are combined with the Gunn and Oke data on high-redshift clusters, a formal value (without accounting for any evolution) of q0=-0.55±0.45 (1σ) is found. File Summary:
