活动星系核和类星体：为什么50年后仍然是一个谜？
Active Galactic Nuclei and Quasars: Why Still a Puzzle after 50 years?
摘要：
本文的第一部分是对类星体及其近亲活动星系核（AGN）的历史和物理介绍。在第二部分中，我认为，自从它们在50年前被发现以来，我们在理解它们方面的进展一直不令人满意，事实上有些虚幻，其中很大一部分原因是研究界普遍缺乏批判性思维。如果其他领域没有遭受类似的失败，那将是非常令人惊讶的。
英文摘要：
The first part of this article is a historical and physical introduction to quasars and their close cousins, called Active Galactic Nuclei (AGN). In the second part, I argue that our progress in understanding them has been unsatisfactory and in fact somewhat illusory since their discovery fifty years ago, and that much of the reason is a pervasive lack of critical thinking in the research community. It would be very surprising if other fields do not suffer similar failings.
