Both the [C II] and continuum are detected and spatially resolved. The [C II] line is ∼1.5 times more extended than the continuum emission, showing an elongated and complex structure of approximately 3.2 kpc × 6.4 kpc. Two separate peaks are clearly seen (≳6σ each) in three 100 km s<SUP>-1</SUP> width [C II] channel maps. The velocity field of the [C II] gas does not show evidence of a coherent rotation field but rather chaotic motion reminiscent of an ongoing merger.STAMPAenThe z = 7.54 Quasar ULAS J1342+0928 Is Hosted by a Galaxy MergerArticle10.3847/2041-8213/ab36592-s2.0-85071074890000481538800003https://iopscience.iop.org/article/10.3847/2041-8213/ab36592019ApJ...881L..23BFIS/05 - ASTRONOMIA E ASTROFISICA
