The current knowledge on the formation and evolution of
galaxies raises a large number of questions, to which the scientists
in the group are attempting to answer using observations
and theoretical modelling
Have the proprerties of galaxies been acquired very early-on or at later times ?
What is the nature of the energetic
phenomena such as active nuclei and radio emission within galaxies ?
Which links can be established with the formation and
evolution of central massive black holes ?
What is the relationship between these phenomena and the stellar formation in galaxies ?
Are the properties of nearby galaxies observed in the UV and
visible transposable to the properties of distant galaxies in the IR,
and at sub-millimeter and millimeter wavalenths ? What are the
implications on the determination of the age and
evolution of these differents objets ?
Which types of galaxies are detected preferentially at mid-IR, far-IR, and sub-millimeter wavelenths,
and what has been the contribution of these galaxies to the history of
star formation ?
What is the impact of physical processes such as conduction and magnetic
fields onto the evolution of galaxy properties ?
