The dark side of star formation in galaxy clusters: spectroscopic follow-up of clusters observed with ISOCAM
Dario Fadda, Pierre-Alain Duc
The evolution of galaxies in cluster environments can be studied using mid-IR observations which trace star forming regions hidden by dust. The optical follow-up of A1689 (z=0.2),…

Dwarf Galaxies and Star Clusters in Tidal Tails
Peter M. Weilbacher, Uta Fritze-von Alvensleben, Pierre-Alain Duc
We summarize the properties of tidal dwarf candidates in a sample of interacting galaxies and classify objects in tidal tails depending on their morphological appearance. New high-…

Spectrophotometric Investigation of a Sample of Tidal Dwarf Galaxies
Peter M. Weilbacher, Pierre-Alain Duc
We define a Tidal Dwarf Galaxy (TDG) as a self-gravitating entity of dwarf-galaxy mass built from tidal material expelled during interactions. We then summarize our findings on bro…
