Highest-ranked model A of ESO 137−001. Upper panel: Hα is shown in color; X-ray in dark gray contours; CO in white contours; and stellar content in black contours. The relative contours are the same as in Fig. 4, i.e., Hα: logarithmic transfer function with 15 contour levels; X-ray and CO: square root transfer function with 15 contour levels. Lower panel: Hα velocity field. The colors are the same as in Fig. 4. The corresponding time evolution and that of the mass surface densities of the different gas phases can be found be found in online movies.
