1988ApJ...329L..65H DISCORDANT REDSHIFTS IN COMPACT GROUPS OF GALAXIES PAUL HICKSON AND ENRICO KINDL Department of Geophysics and Astronomy, University of British Columbia AND JOHN P. HUCHRA Harvard-Smithsonian Center for Astrophysics Received 1988 February 17; accepted 1988 March 24 ABSTRACT We estimate the field galaxy contamination of galaxy quintets in Hickson's catalog of compact groups by computing the probability of the random projection of field galaxies on or near quartets in the catalog. This is done by Monte Carlo simulations based on galaxy counts in fields surrounding the quartets. Thirty-five percent of all quintets are predicted to contain a single discordant redshift due to a projected field galaxy. This agrees with the observed number of four discordant quintets in 10. These results are consistent with the cosmological interpretation of galaxy redshifts. Subject headings: galaxies: clustering - galaxies: redshifts
