There are two fundamentally different physical origins of faint satellite galaxies: cosmological substructures that contain shining baryons and the fragmentation of gas-rich tidal arms thrown out from interacting galaxies during hierarchical structure formation. The latter tidal dwarf galaxies (TDGs) may form populations with correlated orbital angular momenta about their host galaxies. The existence of TDGs is a stringent necessity because they arise as a result of fundamental physical...[Show more]
