Streamline model of the red- (top) and blueshifted (bottom) sides of the gas bridge. The left panel shows the integrated intensity of DCN (3−2) in grayscale and the velocity map in color. The black contours are the 1.4 mm continuum with levels at 5, 10, 20, 40, 80, and 160×σ_cont (σ_cont=0.94 mJy beam⁻¹). The synthesized beam of the NOEMA line and continuum data is shown in the bottom left and right panels, respectively. A scale bar is shown in the top left corner. The right panel shows the kernel density estimate of the observed velocity profile in grayscale as a function of projected distance and the streamline model in red. The projected trajectory of the streamline model is highlighted in red in the left panels as well. The position at which the streamline model reaches the centrifugal radius is marked by the red triangle.
