Two orthogonal views each of the stars (left) and gas (right) in the best model at ﹩t=140﹩ Myr. Gas particles from galaxy A are shown as dots, while the gas distribution of galaxy B is shown by a few representative contours. The plots in the top panels show that the primary’s gas bridge is concentrated on the north (top) side of the tidal bridge, while the old stars are more smoothly distributed. This shows the gas‐star offset in this component of the bridge. The gas tail from B (not shown) is located in true thin filaments stretching between the two galaxies. The plots in the bottom panel show that this is not the case for the gas bridge from A, which remains near the A disk.
