Stellar Populations of a Sample of Tidal Dwarf Galaxies
Peter M. Weilbacher, Uta Fritze-v. Alvensleben, Pierre-Alain Duc
We investigate the stellar populations of a sample of Tidal Dwarf Galaxies, combining observations and evolutionary synthesis models to try and reveal their formation mechanism. On…
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…
Spectrophotometric Evolutionary Models for Tidal Dwarfs
Peter M. Weilbacher, Uta Fritze-v. Alvensleben
We describe our procedure to model Tidal Dwarf Galaxies in the context of our evolutionary synthesis code. Our analysis shows strong contributions of gaseous emission lines to opti…
Tidal dwarf candidates in a sample of interacting galaxies
Peter M. Weilbacher, P. -A. Duc, U. Fritze-v. Alvensleben +2
We present deep optical B, V, R images of a sample of 10 interacting systems which were selected for their resemblance to disturbed galaxies at high redshift. Photometry is perform…
