Photometric Properties of Galaxy Population in the Cluster EIS 0048 - 2942 at z ∼ 0 . 64
Deep photometric data in the V-, R-, I-, zand K-bands for the cluster of galaxies EIS 0048-2942 are used to investigate the properties of the galaxy populations at z ∼ 0.64 in a field of 2.5 × 2.5 Mpc. The sample of candidate cluster members (N = 171) is selected by the photometric redshift technique and is complete up to I = 22.5. Galaxies were classified as spheroids and disks according to th...
متن کاملThe intermediate - redshift galaxy cluster CL 0048 - 2942 . Stellar populations
We present a detailed study of the cluster CL 0048-2942, located at z ∼ 0.64, based on a photometric and spectro-scopic catalogue of 54 galaxies in a 5 × 5 arcmin 2 region centred in that cluster. Of these, 23 galaxies were found to belong to the cluster. Based on this sample, the line-of-sight velocity dispersion of the cluster is approximately 680 ± 140 km/s. We have performed stellar populat...
متن کاملUV – NIR Restframe Luminosity Functions of the Galaxy Cluster EIS 0048 at z ∼ 0 . 64 ⋆
We derive the galaxy luminosity functions in V-, R-, I-, and K-bands of the cluster EIS 0048 at z ∼ 0.64 from data taken at the ESO Very Large Telescope. The data span the restframe wavelength range from UV, which is sensitive to even low rates of star formation, to the NIR, which maps the bulk of the stellar mass. By comparison of our data and of previous results with pure luminosity evolution...
متن کاملPhotometric Properties of Low Redshift Galaxy Clusters
A recent comprehensive photometric survey of 45 low-z X-ray selected Abell clusters (López-Cruz 1997) has measured significant variations in the faint end slope of the luninosity function (LF). This result has indicated that dwarf galaxies (dGs) have different mixtures in relation with the cluster environment. Clusters having a central " cD-like " galaxy have a flatter faint end slope than non-...
متن کاملPhotometric Properties of Low-redshift Galaxy Clusters
A comprehensive multicolor survey was undertaken to investigate global optical properties of Abell clusters of galaxies. This survey was christened the LowRedshift Cluster Optical Survey (LOCOS). LOCOS was devised to search for patterns of galaxy evolution induced by the environment. The generated data base contains accurate deep CCD photometric measurements (Kron-Cousins R, B and I) for a samp...
