| Abstract: |
Near-infrared (NIR, 1.03-1.35 μm) high- and medium-resolution spectra of the quasi-stellar object (QSO) APM 08279+5255 were obtained with Subaru IRCS Echelle spectroscopy. We clearly detected Mg II λλ 2796,2803 absorption lines at zabs=3.5023, which is the first detection of “weak Mg II system” at high-redshift (z> 3). We briefly discuss some preliminary results on the metalliciy and abundance of this system. |
