摘要：

We present the results of the analysis of the chemical abundances and kinematics in a high-redshift damped Ly-alpha (DLA) system towards the quasar APM 1311 J0307-4945 observed during the Commissioning of UVES on the 8.2m ESO VLT Kueyen telescope at Cerro Paranal Observatory. With a redshift z(abs) = 4.466 and a total neutral hydrogen column density log AT(HI) = 20.67 +/- 0.09, it is the most distant DLA system known to the present date, observed when the Universe was as young as 1.3(1) Gyr.
