Arp 220 W and E nuclear spectra. The spectra were extracted from a circular aperture of radius 3 spaxels (corresponding to 0.15″) and are reported in units of flux density as a function of rest-frame wavelength. Red dashed vertical lines identify H2 lines; black dashed lines identify ionized gas transitions. Gold-filled areas mark the position of the main CO stellar absorption lines.
