Abstract

We analyzed a sample of 44 candidates for Tidal Dwarf Galaxies(TDGs) previously selected on optical imaging with low resolution spectroscopy. Most of the TDG candidates have the same redshift as the interacting system, 3 of them very likely are low metallicity dwarf galaxies in projection, and 13 show signs of kinematics decoupled from their hosting tidal tail. Subsequent NIR photometry in combination with evolutionary synthesis modeling allows us to derive stellar masses, star formation rates, and the ratio of old to young stars within each TDG candidate.
