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…
ce-61: a Tidal Dwarf Galaxy in the Hercules cluster?
W. van Driel, P. -A. Duc, P. Amram +9
A candidate Tidal Dwarf Galaxy, ce-61, was identified in the merger system IC 1182 in the Hercules supercluster. The multi-wavelength data we obtained so far do not prove, however,…
Deriving the redshift of distant galaxies with Gamma-Ray Burst transient edges
E. Le Floc'h, P. -A. Duc, I. F. Mirabel
Cosmological Gamma-Ray Bursts (GRBs) offer a unique perspective to probe the evolution of distant galaxies. We discuss one of the multiple benefits of this approach, i.e. the detec…
Molecular gas in the intergalactic medium of Stephan's Quintet
Ute Lisenfeld, Stephane Leon, Jonathan Braine +3
Stephan's Quintet (SQ) is a Hickson Compact Group well known for its complex dynamical and star formation history and its rich intergalactic medium (IGM). In order to study the ext…
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),…
