Beginning of ReadMe : J/A+A/416/839 Radial velocities of A2219 galaxies (Boschin+, 2004) ================================================================================ Internal dynamics of the radio-halo cluster A2219: a multiwavelength analysis. Boschin W., Girardi M., Barrena R., Biviano A., Feretti L., Ramella M. <Astron. Astrophys. 416, 839 (2004)> =2004A&A...416..839B ================================================================================ ADC_Keywords: Clusters, galaxy ; Radial velocities ; Photometry Keywords: galaxies: clusters: general - galaxies: clusters: individual: Abell 2219 - galaxies: distances and redshifts - intergalactic medium - cosmology: observations Abstract: We present the results of the dynamical analysis of the rich, hot, and X-ray very luminous galaxy cluster A2219, containing a powerful diffuse radio-halo. Our analysis is based on new redshift data for 27 galaxies in the cluster region, measured from spectra obtained at the Telescopio Nazionale Galileo (TNG), with the addition of other 105 galaxies recovered from reduction of CFHT archive data in a cluster region of about 5-arcmin radius (about 0.8Mpc/h at the cluster distance) centered on the cD galaxy. The investigation of the dynamical status is also performed by using X-ray data stored in the Chandra archive. Further, valuable information comes from other bands - optical photometric, infrared, and radio data - which are analyzed and/or discussed, too. Our analyses support the view of the connection between extended radio emission and merging phenomena in galaxy clusters. Description: Spectroscopic redshifts for 132 galaxies in the central region of the galaxy cluster Abell 2219 are presented. For each galaxy equatorial coordinates, total R magnitude and B-R colour (Harris filters), and velocity are given. Where available, we also give a code for the spectral classification.
