DENG, Xin-Fa  e  ZOU, Si-Yu. Environmental dependence of all five band luminosities for SDSS-III/boss galaxies in the SDSS DR9. Rev. mex. astron. astrofis [online]. 2014, vol.50, n.2, pp.181-188. ISSN 0185-1101.

Using the CMASS sample with a redshift of 0.44≤ z ≤0.59, we investigate the environmental dependence of all five band luminosities in the CMASS sample of the Sloan Digital Sky Survey Data Release 9 (SDSS DR9). To decrease the radial selection effect, we divide the CMASS sample into several subsamples with a redshift binning size of Δz = 0.01, and we analyze the environmental dependence of the five band luminosities of subsamples in each redshift bin. It is found that all five band luminosities are very weakly correlated with the local environment.
