Fig. 17

image

MUSE spectrum of the starburst galaxy (top) and spectrum of a nearby sky background (bottom). The brightest lines are identified. The very bright [O i] λ5577.34 telluric line appears, by chance, in the galaxy spectrum but not in the sky spectrum, because it is not subtracted correctly in most parts of the datacube. The inset is the monochromatic MUSE image at 6658.75 Å (redshifted [O iii] λ5007) centered on the QSO, showing the position of the emission line galaxy; the image is 30′′ across; the bright object near the top is a Galactic red giant star.
