Molecular gas and star formation in the Tidal Dwarf Galaxy VCC 2062
The physical mechanisms driving star formation (SF) in galaxies are still not fully understood. Tidal dwarf galaxies (TDGs), made of gas ejected during galaxy interactions, seem to be devoid of dark matter and have a ...
Gas dynamics in tidal dwarf galaxies : disc formation at z=0
Tidal dwarf galaxies (TDGs) are recycled objects that form within the collisional debris of interacting/merging galaxies. They are expected to be devoid of non-baryonic dark matter, since they can form only from dissipative ...
Studying the spatially resolved Schmidt-Kennicutt law in interacting galaxies : The case of Arp 158
Context. Recent studies have shown that star formation in mergers does not seem to follow the same Schmidt-Kennicutt relation as in spiral disks, presenting a higher star formation rate (SFR) for a given gas column density. ...
Collisional Debris as Laboratories to Study Star Formation
In this paper we address the question of whether star formation (SF) is driven by local processes or the large-scale environment. To do so, we investigate SF in collisional debris where the gravitational potential well and ...
