We used two volume-limited active galactic nucleus (AGN) host galaxy samples constructed by Deng & Wen (2020, RMxAA, 56, 87), and explored the environmental dependence of the stellar mass of AGN host galaxies. In the luminous volume-limited AGN host galaxy sample, the stellar mass of AGN host galaxies apparently depends on local environments: high mass AGN host galaxies exist preferentially in the dense regions of the universe, while low mass AGN host galaxies are located preferentially in low density regions. But in the faint volume-limited AGN host galaxy sample, this dependence is fairly weak. We also examined the dependence of the clustering properties of AGN host galaxies on the stellar mass by cluster analysis, and found that in the luminous volume-limited AGN host galaxy sample, low mass AGN host galaxies preferentially form isolated galaxies, close pairs, and small groups, while high mass AGN host galaxies preferentially inhabit the dense groups and clusters. A substantial dependence of the clustering properties of AGN host galaxies on the stellar mass is also observed in the faint volume-limited AGN host galaxy sample, which is inconsistent with the environmental dependence of the stellar mass of AGN host galaxies in the faint volume-limited AGN host galaxy sample. This is likely due to the galaxy number of the faint volume-limited AGN host galaxy sample being too small to ensure an ideal statistical analysis.

活动星系核宿主星系恒星质量的环境依赖性和活动星系核宿主星系的星团特性对恒星质量的依赖性

我们使用了由 Deng & Wen (2020, RMxAA ) 构建的两个体积受限的活动星系核 (AGN) 宿主星系样本, 56, 87)，并探索了 AGN 宿主星系的恒星质量对环境的依赖性。在发光体积受限的 AGN 宿主星系样本中，AGN 宿主星系的恒星质量显然取决于局部环境：高质量 AGN 宿主星系优先存在于宇宙的密集区域，而低质量 AGN 宿主星系优先位于低质量 AGN 宿主星系。密度区域。但在体积有限的微弱 AGN 宿主星系样本中，这种依赖性相当弱。我们还通过聚类分析检验了 AGN 宿主星系的聚集特性对恒星质量的依赖性，发现在发光体积受限的 AGN 宿主星系样本中，低质量的 AGN 宿主星系优先形成孤立星系、近对星系和小星系。团体，而高质量 AGN 宿主星系则优先居住在密集的群体和星团中。在微弱的体积受限的 AGN 宿主星系样本中也观察到 AGN 宿主星系的聚集特性对恒星质量的显着依赖性，这与微弱体积受限的 AGN 宿主星系的恒星质量的环境依赖性不一致。 AGN 宿主星系样本。这可能是由于体积有限的微弱 AGN 宿主星系样本的星系数量太小，无法确保理想的统计分析。这与微弱体积受限的 AGN 宿主星系样本中 AGN 宿主星系的恒星质量的环境依赖性不一致。这可能是由于体积有限的微弱 AGN 宿主星系样本的星系数量太小，无法确保理想的统计分析。这与微弱体积受限的 AGN 宿主星系样本中 AGN 宿主星系的恒星质量的环境依赖性不一致。这可能是由于体积有限的微弱 AGN 宿主星系样本的星系数量太小，无法确保理想的统计分析。
