J/ApJ/693/617 Ellipticities of cluster early-type galaxies (Holden+, 2009) ================================================================================ The ellipticities of cluster early-type galaxies from z ~ 1 to z ~ 0: no evolution in the overall distribution of bulge-to-disk ratios. Holden B.P., Franx M., Illingworth G.D., Postman M., van der Wel A., Kelson D.D., Blakeslee J.P., Ford H., Demarco R., Mei S. =2009ApJ...693..617H ================================================================================ ADC_Keywords: Clusters, galaxy ; Galaxies, optical ; Photometry, VRI ; Redshifts Keywords: galaxies: clusters: general - galaxies: clusters: individual (CL 1226.9+3332) - galaxies: elliptical and lenticular, cD - galaxies: evolution - galaxies: fundamental parameters - galaxies: photometry Abstract: We have compiled a sample of early-type cluster galaxies from 00.3 clusters with high-quality space-based imaging and a comparable sample of 210 galaxies in 10 clusters at z<0.05. We select early-type galaxies (elliptical and S0 galaxies) that fall within the cluster R_200_, and which lie on the red-sequence in the magnitude range -19.3>M_B_>-21, after correcting for luminosity evolution as measured by the fundamental plane. Description: Of the clusters discussed here, only CL J1226+33 has no previously published redshift catalog beyond the six galaxies listed in the discovery paper (Ebeling et al. 2001ApJ...548L..23E). We have collected redshifts for 21 new members in the central region of the cluster, along with 10 more galaxies outside of the region covered by the ACS imaging. The redshift range we used for membership excludes two galaxies at z~0.91. Data were taken using the DEIMOS spectrograph on Keck II.
