J/A+A/506/1071 Galaxy morphology in 5 medium redshift clusters (Ascaso+, 2009)

The bright galaxy population of five medium redshift clusters. II. Quantitative galaxy morphology. Ascaso B., Aguerri J.A.L., Moles M., Sanchez-Janssen R., Bettoni D. <Astron. Astrophys., 506, 1071-1082 (2009)> =2009A&A...506.1071A
ADC_Keywords: Clusters, galaxy ; Galaxies, photometry ; Morphology Keywords: galaxies: clusters: general - galaxies: structure - cosmology: observations Abstract: Following the study presented in our previous paper, based on the Nordic Optical Telescope (NOT) sample, which consists of five clusters of galaxies within the redshift range 0.18≤z≤0.25 imaged in the central 0.5-2Mpc in very good seeing conditions, we have studied the quantitative morphology of their bright galaxy population. We analyzed the surface brightness profiles of the galaxy population in those clusters, after performing simulations in order to check the reliability of the fits. We also derived a quantitative morphological classification. File Summary:

Note (1): The five clusters are A1643, A1878, A1952, A2111 and A2658. Note (2): Galaxies identified in Simbad as <[AMA2008] ANNNN> Note (3): Red (R) galaxies are located within 0.2mag from the CMR of the host cluster and Blue (B) galaxies are bluer than 0.2mag the CMR of the cluster.
