标题： Environmental Dependence of the Nature of Gaseous Envelopes of Galaxies at z < 1

摘要： 我们对在类星体场中检测到的Lyman-alpha吸收系统起源进行了新的统计研究。 主要目标是研究星系与Lyman-alpha吸收系统之间关系的环境依赖性。 我们发现，星系在形成其晕中的Lyman-alpha吸收体方面没有环境依赖性。 相反，Lyman-alpha吸收体在其所处环境中也没有偏好。 显示英文摘要

摘要： We present new statistical study on the origin of Lyman-alpha absorption systems that are detected in QSO fields. The primary objective is to investigate environmental dependence of the relationship between galaxies and Lyman-alpha absorption systems. We find that galaxies exhibit no environmental dependence in giving rise to Lyman-alpha absorbers in their halos. Conversely, Lyman-alpha absorbers do not exhibit preference as to the environment where they reside.
