Beginning of ReadMe : J/ApJ/613/841 Redshifts in A2125 (Miller+, 2004) ================================================================================ The dynamics of A2125. Miller N.A., Owen F.N., Hill J.M., Keel W.C., Ledlow M.J., Oegerle W.R. <Astrophys. J., 613, 841-850 (2004)> =2004ApJ...613..841M ================================================================================ ADC_Keywords: Clusters, galaxy ; Redshifts Keywords: galaxies: clusters: individual (A2125) - galaxies: evolution - galaxies: kinematics and dynamics Abstract: We present 371 galaxy velocities in the field of the very rich cluster A2125 (z 0.25). These were determined using optical spectroscopy collected over several years from both the WIYN 3.5m telescope and NOAO Mayall 4m telescope. Prior studies at a variety of wavelengths (radio, optical, and X-ray) have indicated that A2125 is a likely cluster-cluster merger, a scenario that we are able to test using our large velocity database. We identified 224 cluster galaxies, which were subjected to a broad range of statistical tests using both positional and velocity information to evaluate the cluster dynamics and substructure. The tests confirmed the presence of substructures within the A2125 system at high significance, demonstrating that A2125 is a complex dynamical system. Comparison of the test results with existing simulations strengthens the merger hypothesis and provides clues about the merger geometry and stage. The merger model for the system can reconcile A2125's low X-ray temperature and luminosity with its apparently high richness and might also explain A2125's high fraction of active galaxies identified in prior radio and optical studies. Description: Observations of A2125 were performed by W. R. Oegerle and J. M. Hill using the Hydra multifiber spectrograph on the WIYN 3.5m telescope during a pair of observing runs in 1996. Three fiber configurations were observed during 1996 April 16-18, and a fourth was observed during 1996 May 20-22. Additional spectroscopy using Hydra on the WIYN telescope was performed in the queue observing mode over several nights from 2000 March through May.
