![Companion [C ii] emitter candidate found in the J2228$+$0152 field. These velocity channel maps were generated from the original resolution [C ii] cube (angular resolution = ${0{^{\prime \prime}_{.}}44}$$\times$${0{^{\prime \prime}_{.}}40}$; bottom-left ellipses). The candidate emitter is indicated by the arrow, which is ${\sim } 7$ kpc away from the central quasar (star). The contour steps are $-$3, $-$2, 2, 3, 4, 5 $\sigma$ (1 $\sigma$ = 0.10 mJy beam$^{-1}$ at a velocity resolution of ${\sim } 100$ km s$^{-1}$). The numbers in the top-left corner indicate the velocities relative to the quasar systemic velocity.
