Issue Date: | 2019 | Journal: | THE ASTROPHYSICAL JOURNAL | Number: | 881 | Issue: | 1 | First Page: | L23 | Abstract: | We present ALMA 0.″28 × 0.″20 (1.4 kpc × 1.0 kpc) resolution observations of the [C II] 158 μm line and underlying dust continuum in the host galaxy of the most distant quasar currently known, ULAS J1342+0928 at z = 7.5413. 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. | URI: | http://hdl.handle.net/20.500.12386/28582 | URL: | https://iopscience.iop.org/article/10.3847/2041-8213/ab3659 | ISSN: | 0004-637X | DOI: | 10.3847/2041-8213/ab3659 | Bibcode ADS: | 2019ApJ...881L..23B | Fulltext: | open |
