Molecular gas and star formation in the Tidal Dwarf Galaxy VCC 2062
(2016-06-01)
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 ...
Studying the spatially resolved Schmidt-Kennicutt law in interacting galaxies : The case of Arp 158
(2011-09)
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
(2009)
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 ...

Abundant molecular gas in the intergalactic medium of Stephan's Quintet
(2002-11)
Stephan's Quintet (SQ) is a system consisting of at least four interacting galaxies which is well known for its complex dynamical and star formation history. It possesses a rich intergalactic medium (IGM), where hydrogen ...
