论文摘要
在本文中，我们总结了埃塞俄比亚目前正在进行的研究，而活性星系和活性银河系核（AGN）的物理学和物理学中正在进行的研究。这项研究集中在一些仍然开放的问题上，例如：超硬X射线的恒星年龄和人群是什么样的X射线检测到的AGN和AGN与宿主星系之间的联系？绿谷中的星系以及AGN在星系进化中的作用？这些问题中的每一个都是在将简要介绍的一个特定项目下开发的。这些项目涉及埃塞俄比亚，卢旺达，南非，乌干达，坦桑尼亚，西班牙，意大利和智利之间的6名博士学位和3名MSC学生以及合作。我们的目标是：首先，为我们对AGN的一般知识做出贡献，其次是为埃塞俄比亚和东非的天文学和科学发展做出贡献。
In this paper we summarise the research that is currently going on in Ethiopia and East-Africa in extragalactic astronomy and physics of active galaxies and active galactic nuclei (AGN). The study is focused on some of the still open questions such as: what are the stellar ages and populations of ultra hard X-ray detected AGN and connection between AGN and their host galaxies?, what are the properties of AGN in galaxy clusters and the role that environment has in triggering nuclear activity?, what are the morphological properties of AGN and how precisely we can deal with morphological classification of active galaxies?, what are the properties of galaxies in the green valley and the role of AGN in galaxy evolution?, and what are the properties of radio-loud and radio-quiet quasars (QSO) and dichotomy between the two?. Each of these questions has been developed under one specific project that will be briefly introduced. These projects involve 6 PhD and 3 MSc students and collaborations between Ethiopia, Rwanda, South Africa, Uganda, Tanzania, Spain, Italy, and Chile. With all projects we aim: first, to contribute to our general knowledge about AGN, and second, to contribute to the development in astronomy and science in Ethiopia and East-Africa.
