  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.
