埃塞俄比亚和东非通过星系核活动发展天文学
Development in astronomy in Ethiopia and East-Africa through nuclear activity in galaxies
摘要:
在本文中,我们总结了目前正在进行的研究,在埃塞俄比亚和东非的河外天文学和活动星系和活动星系核(AGN)的物理。这项研究的重点是一些仍然悬而未决的问题,如:什么是恒星的年龄和人口的超硬X射线检测活动星系核和活动星系核之间的连接和他们的宿主星系?星系团中活动星系核的性质是什么,以及环境在触发核活动中的作用?活动星系核的形态特征是什么?我们如何精确地处理活动星系的形态分类?绿谷星系的性质是什么?活动星系核在星系演化中的作用是什么?射电强和射电静类星体(QSO)的性质以及两者之间的二分法是什么?每一个问题都是在一个具体项目下提出的,下面将简要介绍。这些项目涉及6名博士生和3名硕士生,以及埃塞俄比亚、卢旺达、南非、乌干达、坦桑尼亚、西班牙、意大利和智利之间的合作。我们所有的项目都旨在:首先,有助于我们对AGN的一般知识,其次,有助于埃塞俄比亚和东非天文学和科学的发展。
英文摘要:
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.
