DENG, Xin-Fa  e  WEN, Xiao-Qing. Environmental Dependence of Age, Stellar Mass, Star Formation Rate and Stellar Velocity Dispersion of Active Galactic Nucleus Host Galaxies. Rev. mex. astron. astrofis [online]. 2021, vol.57, n.1, pp.157-166.  Epub 30-Set-2021. ISSN 0185-1101.  https://doi.org/10.22201/ia.01851101p.2021.57.01.11.

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 age, stellar mass, the star formation rate (SFR) and stellar velocity dispersion of AGN host galaxies. We divide the whole apparent-magnitude limited AGN sample into many subsamples with a red-shift binning size of Δz = 0:01, and analyse the environmental dependence of these galaxy properties of subsamples in each redshift bin. It turns out that these parameters of AGN host galaxies seemingly only have a weak environmental dependence.
