Mid-infrared imaging of active galaxies: active nuclei and embedded star clusters
E. Galliano, D. Alloin, E. Pantin, P.O. Lagage, O. Marco
High resolution mid-infrared images of a set of nine active galaxies are presented. Among other features, the images unveil circumnuclear populations of previously unknown mid-infrared sources, coincident with radio sources. They are interpreted in terms of embedded young and massive star clusters.  A new method is devised to derive their ages and masses.
