Description:
We present the first high-resolution (6.2 to 7.7km/s FWHM) spectra of
the APM BR J0307-4945 quasar at zem=4.73 obtained with UVES on the
8.2m VLT Kueyen telescope. We focus our analysis on a damped
Lyman-α system at zabs=4.466, the most distant DLA system
known to the present date, observed when the age of the universe was
only 1.3Gyr. The following table lists the wavelengths and equivalent
widths for all absorption-line features (except the telluric lines)
redwards of the quasar Ly-α emission detected at 4σ in
equivalent width. The transition names and approximate redshifts are
specified for the features we successfully identified. About 80% of
the absorption lines redwards of the quasar Ly-α emission have
been identified, corresponding to 13 metal-line systems.
