Multiwavelength observations of ESO 137−001. Upper panel: MUSE Hα is shown in color (Sun et al. 2022; Luo et al. 2023); Chandra X-ray in black contours (Sun et al. 2010); and ALMA CO in white contours (Jáchym et al. 2019). It appears that the X-ray stripping front is ahead of the Hα stripping front because of the large spatial smoothing scale of the X-ray image, but in reality, the X-ray and Hα stripping fronts are at the same position, as shown in Fig. 2 of Luo et al. (2023). Lower panel: MUSE Hα velocity field (Sun et al. 2022). The color scale corresponds to the LOS velocities with respect to the systemic velocity in km s⁻¹. At a distance of 70 Mpc 30″ correspond to about 10 kpc. The size of the images is 80 kpc × 60 kpc.
