Neutral hydrogen gas in interacting galaxies: the NGC 6221/6215 galaxy group.
KORIBALSKI B. and DICKEY J.M.
Abstract (from CDS):
The brightest part of the HI bridge lies roughly halfway between the interacting galaxies, indicating that bridge gas close to NGC 6221 and 6215 may have fallen back to the galaxies. The asymmetric extensions to the HI envelope of NGC 6221 are likely to be reaccreted gas, still settling in. Also, the peculiar velocity field of NGC 6215 may be explained by accreted bridge material settling into a plane offset from the old disc.
