- Title
Investigation of the Environmental Dependence of Galaxy Age in the CMASS Galaxy Sample of SDSS DR12.

- Abstract
In this study, I investigate the environmental dependence of galaxy age in the CMASS sample of the Sloan Digital Sky Survey Data Release 12 (SDSS DR12). It is found that galaxy age is very weakly correlated with the local environment. Considering the weak stellar mass-density relation of CMASS galaxies, it has been suggested that it is likely a combination of a strong age-stellar mass relation and a weak stellar mass-density relation.
