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…
Identifying old Tidal Dwarf Galaxies in Simulations and in the Nearby Universe
Pierre-Alain Duc, Frederic Bournaud, Frederic Masset
Most Tidal Dwarf Galaxies (TDGs) so-far discussed in the literature may be considered as young ones or even newborns, as they are still physically linked to their parent galaxies b…
Halpha Kinematics of Tidal Tails in Interacting Systems: Projection Effects and Dark Matter in TDGs
P. Amram, F. Bournaud, P. -A. Duc
Several interacting systems exhibit at the tip of their long tidal tails massive condensations of atomic hydrogen, which may be the progenitors of Tidal Dwarf Galaxies. Because, qu…
Molecular Gas in Tidal Dwarf Galaxies: On-going Galaxy Formation
J. Braine, P. -A. Duc, U. Lisenfeld +3
We investigate the process of galaxy formation as can be observed in the only currently forming galaxies -- the so-called Tidal Dwarf Galaxies, hereafter TDGs -- through observatio…
