A top-down scenario for the formation of massive Tidal Dwarf Galaxies
Pierre-Alain Duc, Frederic Bournaud, Frederic Masset
Among those objects formed out of collisional debris during galaxy mergers, the prominent gaseous accumulations observed near the tip of some long tidal tails are the most likely t…
Molecular and ionized gas in the tidal tail in Stephan's Quintet
U. Lisenfeld, J. Braine, P. -A. Duc +3
We have mapped with the IRAM interferometer at Plateau de Bure (PdBI) the 12CO emission towards intergalactic star forming regions located in the tidal tail stemming from NGC7319,…
Kinematics of tidal tails in interacting galaxies: Tidal Dwarf Galaxies and projection effects
F. Bournaud, P. -A. Duc, P. Amram +2
The kinematics of tidal tails in colliding galaxies has been studied via Fabry-Perot observations of the Halpha emission. With their large field of view and high spatial resolution…
Luminous Infrared Starbursts in a Cluster of Galaxies
Pierre-Alain Duc, Dario Fadda, Bianca Poggianti +6
Analysing mid--infrared ISOCAM images of the cluster of galaxies J1888.16CL, we identified among its members several particularly active galaxies with total infrared luminosities w…
VLA HI and OVRO CO Interferometry of a Tidal Dwarf Galaxy
Elias Brinks, Pierre-Alain Duc, Fabian Walter
We present high resolution interferometric observations of the cool atomic and cold molecular ISM of the TDG candidate Arp 245N, an object resembling a dwarf galaxy in the northern…
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…
