Associated absorption system of C IV+N V+Si IV along the line of sight to J2007-0416 at z_abs = 5.506, corresponding to v_abs = −1166 km s⁻¹. Spectral errors are reported as a gray-shaded region. The associated Lyα absorption line is also displayed. Higher-order Lyman lines are not reported as they are heavily blended with other hydrogen lines; hence they do not provide any additional information on the absorption system. This system is particularly interesting, as it displays partial coverage effects on both C IV and N V absorption systems.
