]]> RESUMEN
El objetivo de este estudio es examinar la dependencia ambiental de los colores u - r, u - g, g - r, r - i e i - z en la muestra de baja z del Sloan Digital Sky Survey Data Release 10 (SDSS DR10). Para disminuir el efecto de selección radial, divido la muestra de baja z en submuestras agrupadas en intervalos de ∆z=0.01 y analizo la dependencia ambiental de los colores para estas submuestras en cada intervalo de corrimiento al rojo. Los resultados estadísticos indican que los cinco colores de la muestra de baja z están levemente correlacionados con las propiedades ambientales locales, lo cual coincide con lo encontrado para galaxias principales a z > 0.15 y para galaxias GMASS.
ABSTRACT
The aim of this study is to examine the environmental dependence of the u - r, u - g, g - r, r - i and i - z colors in the loz z sample of the Sloan Digital Sky Survey Data Release 10 (SDSS DR10). To decrease the radial selection effect, I divide the low z sample into subsamples with a redshift binning size of ∆z=0.01 and analyze the environmental dependence of colors for these subsamples in each redshift bin. The statistical results show that all five colors of galaxies in the low z sample are weakly correlated with the local environment, which is consistent with the results of main galaxies at z > 0.15 and CMASS galaxies.
Key Words: Galaxies: fundamental parameters — galaxies: statistics.
