J/ApJ/566/103  VIK' photometry and redshifts of galaxy clusters  (Nelson+, 2002)

Revisiting brightest cluster galaxy evolution with the Las Campanas Distant Cluster Survey. Nelson A.E., Gonzalez A.H., Zaritsky D., Dalcanton J.J. <Astrophys. J. 566, 103 (2002)> =2002ApJ...566..103N
ADC_Keywords: Clusters, galaxy ; Photometry, infrared ; Redshifts Keywords: galaxies: clusters: general - galaxies: elliptical and lenticular, cD - galaxies: evolution - galaxies: formation - galaxies: high-redshift - surveys Abstract: We investigate the influence of environment on brightest cluster galaxy (BCG) evolution using a sample of 63 clusters at 0.3≤z≤0.9 drawn primarily from the Las Campanas Distant Cluster Survey and follow-up V, I, and K' photometry. Our data originate from a variety of telescopes and instruments. The cluster sample and observations used here stem from deep optical and infrared follow-up imaging of a small subset of the full catalog that was obtained to aid in the classification of candidates and to develop photometric redshift indicators.
