摘要

利用斯隆数字巡天数据发布12 (SDSS DR12)的明显星等限制活动星系核(AGN)宿主星系样本，我们研究了AGN宿主星系的u-r、u-g、g-r、r-i和i-z颜色对环境的依赖性。我们将整个明显星等受限的AGN样本划分为多个红移盒大小为?z = 0.01的子样本，并分析了每个红移盒中所有五个星系颜色的环境依赖性。结果表明，总体而言，AGN宿主星系的所有五个星系颜色与当地环境的相关性都很弱。

Environmental Dependence of Different Colors of Active Galactic Nucleus (AGN) Host Galaxies

Using the apparent-magnitude limited active galactic nucleus (AGN) host galaxy sample of the Sloan Digital Sky Survey Data Release 12 (SDSS DR12), we investigate the environmental dependence of the u-r, u-g, g-r, r-i and i-z colors of AGN host galaxies. We divide the whole apparent-magnitude limited AGN sample into many subsamples with a redshift binning size of ?z = 0.01, and analyze the environmental dependence of all five galaxy colors of subsamples in each redshift bin. It turns out that overall, all five galaxy colors of AGN host galaxies are weakly correlated with the local environment.

期刊介绍： Astrophysics (Ap) is a peer-reviewed scientific journal which publishes research in theoretical and observational astrophysics. Founded by V.A.Ambartsumian in 1965 Astrophysics is one of the international astronomy journals. The journal covers space astrophysics, stellar and galactic evolution, solar physics, stellar and planetary atmospheres, interstellar matter. Additional subjects include chemical composition and internal structure of stars, quasars and pulsars, developments in modern cosmology and radiative transfer.
