Abstract (from CDS):

We report the detection of the 3P1-3P0 fine-structure line of neutral carbon in the z=4.12 quasar PSS 2322+1944, obtained at the IRAM Plateau de Bure interferometer. The [Ci] 3P1-3P0 line is detected with a signal-to-noise ratio of ∼6 with a peak intensity of ≃2.5mJy and a velocity-integrated line flux of 0.81±0.12Jy.km/s. Assuming an excitation temperature of 43K (equal to the dust temperature), we derive a mass of neutral carbon (corrected for magnification) of M_C I≃1.2x107^M☉. In PSS 2322+1944, the cooling due to C is about 6 times smaller than for CO, whereas the CO and C cooling represents ≃10–4 of the far-infrared continuum and more than half of the cooling due to C+.
