Spatially Resolved Kinematics in the Central 1 kpc of a Compact Star-forming Galaxy at z ∼ 2.3 from ALMA CO Observations

We present high spatial resolution (FWHM ∼ 0 14) observations of the CO(8-7) line in GDS-14876, a compact star-forming galaxy at z = 2.3 with a total stellar mass of log(M /M ) = 10.9. The spatially resolved velocity map of the inner r 1 kpc reveals a continuous velocity gradient consistent with the...
