J/AJ/130/47         Velocities of Cygnus A galaxies              (Ledlow+, 2005)

The cluster of galaxies surrounding Cygnus A. II. New velocities and a dynamic model. Ledlow M.J., Owen F.N., Miller N.A. <Astron. J., 130, 47-54 (2005)> =2005AJ....130...47L
ADC_Keywords: Clusters, galaxy ; Photometry ; Radial velocities Keywords: active - galaxies: clusters: individual (Cygnus A) - galaxies: distances and redshifts - galaxies: individual (Cygnus A) Abstract: We have spectroscopically identified 77 new members of the Cygnus A cluster, bringing to 118 the total number of galaxies consistent with cluster membership.

Note (1): Observation type, defined as follows: Reobs = Reobserved galaxies from Paper 1 (1997ApJ...488L..15O); New = New non-cluster velocities. Magnitudes for non-cluster galaxies are apparent magnitudes calculated for a 5" diameter aperture, and are not corrected for Galactic extinction. Note (2): Flag on HV, defined as follows: a = Emission-line redshift; b = The velocity for this galaxy was incorrect in Paper 1 (1997ApJ...488L..15O).
