ALMA detection of a disc-dominated [C II] emission line at z = 4.6 in the luminous QSO J1554+1937

We present observations and analysis of an unusual [C ii] emission line in the very luminous quasi-stellar object (QSO) SDSS J155426.16+193703.0 at z ~ 4.6. The line is extremely broad (full width at half-maximum 735 km s−1) and seems to have a flat-topped or double-peaked line profile. A velocity m...
