本次调查温和地介绍了我们对星系形成的理解中许多最重要的进展。应该指出的是，有许多主题我没有涵盖，但它们应该构成更完整的调查的一部分。在值得适当讨论的主题中，我将包括星系间气体的再电离、在遥远类星体中观察到的吸收线系统的性质及其在宇宙学中的作用、星系角动量的起源以及许多其他理论主题。下面列出的书籍涵盖了其中的许多主题。调查还强调了新观测设施探索成熟的领域。没有必要列出所有与星系形成问题直接相关的观察结果。这个主题的惊人之处在于，如果当前和下一代望远镜有时间进行研究，则可以通过观察来回答许多问题。许多现在处于可能极限的关键项目应该在新一代望远镜的帮助下变得非常简单。这些设施中最主要的是哈勃太空望远镜、红外太空天文台、先进的 X 射线天文学设施和下一代甚大望远镜。将目前所看到的星系形成的主要问题与十年后的位置进行比较将是很有趣的。
The present survey is a gentle introduction to many of the most important developments in our understanding of the formation of galaxies. It should be noted that there are many topics which I have not covered but which should form part of a more complete survey. Among topics which merit proper discussion I would include the re-ionisation of the intergalactic gas, the nature of the absorption line systems observed in distant quasars and their role in cosmology, the origin of the angular momentum of galaxies and many other theoretical topics. The books listed below cover many of these topics.The survey also highlights areas which are ripe for exploration by the new observing facilities. It is unnecessary to list all the observations one would like to make of direct relevance to the problems of galaxy formation. What is striking about the subject is that many questions have arisen which can be answered by observation if the time is made available for their study by the present and next generation of telescopes. Many key programmes which are now at the very limit of what is possible should become quite straightforward with the new generation of telescopes. Prime among these facilities will be theHubble Space Telescope, the Infrared Space Observatory, theAdvanced X-ray Astronomy Facilityand the coming generation of Very Large Telescopes. It will be intriguing to compare what are currently seen to be the major issues of galaxy formation with the position in ten years time.
