标题： Quest for truly isolated galaxies

摘要： 我描述了从1983年我的莱顿博士论文开始，继续通过一系列关于这一主题不同方面的研究生论文，最后以对找到真正孤立天体的困难的最新描述，尝试识别和理解最孤立的星系。在这一过程中揭示并在此呈现的一些发现的含义是，附近宇宙可能包含许多小的暗物质晕，而其中一些晕可能正在吸积星际气体以形成矮星系。 显示英文摘要

摘要： I describe attempts to identify and understand the most isolated galaxies starting from my 1983 Leiden PhD thesis, continuing through a string of graduate theses on various aspects of this topic, and concluding with an up-to-date account of the difficulty to find really isolated objects. The implication of some of the findings revealed on the way and presented here is that the nearby Universe may contain many small dark-matter haloes, and that some such haloes may possibly be accreting intergalactic gas to form dwarf galaxies.
