We present the results of carrying out multi-object spectroscopy in 10 EIS cluster fields. Based on the list of 345 galaxy redshifts we identify significant 3D-density enhancements. For 9 of the EIS clusters we identify significant 3D-concentrations corresponding to the originally detected cluster candidate. We find redshifts in the range 0.097<= z<=0.257 which is in good agreement with the matched filter estimate of zMF=0.2. We estimate velocity dispersions in the range 219-1160 km s-1 for the confirmed clusters.

Abstract
We present the results of carrying out multi-object spectroscopy in 10 EIS cluster fields. Based on the list of 345 galaxy redshifts we identify significant 3D-density enhancements. For 9 of the EIS clusters we identify significant 3D-concentrations corresponding to the originally detected cluster candidate. We find redshifts in the range 0.097<= z<=0.257 which is in good agreement with the matched filter estimate of zMF=0.2. We estimate velocity dispersions in the range 219-1160 km s-1 for the confirmed clusters.File in questo prodotto:
