HI Recycling: Formation of Tidal Dwarf Galaxies
Pierre-Alain Duc, Elias Brinks
Galactic collisions trigger a number of phenomena, such as transportation inward of gas from distances of up to kiloparsecs from the center of a galaxy to the nuclear region, fuell…
An excess of mid-IR luminous galaxies in Abell 1689?
D. Fadda, D. Elbaz, P. -A. Duc +4
We present the results of infrared observations of Abell 1689 which was observed with ISOCAM, at 6.7\mic and 15\mic, and ISOPHOT at 200\mic. The cluster galaxies detected above a s…
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…
Formation of Molecular Gas in the debris of violent Galaxy Interactions
Jonathan Braine, Ute Lisenfeld, Pierre-Alain Duc +1
In many gravitational interactions between galaxies, gas and stars that have been torn from either or both of the precursor galaxies can collect in 'tidal tails'. Star formation be…
