Fig. A.29

(General comments about the panels as in Fig. A.1.) IRAS 12043-3140 (ESO 440-IG058): this system consists of two galaxies with a nuclear separation of ~6 kpc. The northern galaxy is compact, while the southern source presents several knots in the Hα map. The velocity field of the southern galaxy has two relatively well-defined approaching and receding parts, with the kinematic and photometric axes in relatively good agreement. Its velocity dispersion map reaches the highest values (i.e., σ ~ 250 km s-1) in the northern part, in correspondence of a local maximum of the Hα intensity map. Around that region, a secondary broad component has been found in some spectra . The stellar distribution (i.e., continuum map) of the northern galaxy suggests that it is almost face-on: this could possibly explain the derived relatively low velocity shear (i.e., ~42 km s-1). Its velocity field shows a somewhat irregular pattern. The scale is of 0.468 kpc/′′.
