Dynamics of tidal dwarf galaxies


Abstract: Tidal Dwarf Galaxies (TDGs) are objects born in collisional debris, expelled from galaxy mergers by tidal forces. 
They are dynamically distinct structures within tidal tails, showing evidence of rotation. They have the luminosity and mass of 
dwarf galaxies, but contrary to classical galaxies, do not contain large quantities of dark matter.  
I will review the on-going efforts to  characterize TDGs with  kinematical studies  and numerical simulations of collisions and 
discuss  the similarities / differences of their properties with those those of other low-mass stellar systems, such as the 
merger induced Super Star Clusters, Globular Clusters or even Ultra Compact Dwarf Galaxies.
