The Absorption Spectrum of the QSO PKS 2126-158 (zₑm = 3.27) and the Clustering Properties of Metal Systems

D'Odorico, Valentina

Original · EN

We report the detection of a significant clustering signal on scales Δv < 300 km/s, for a sample of 71 C IV absorbers. This result confirms previous findings and, together with data at lower column density, it points to a trend of decreasing clustering amplitude with decreasing column density, analogous to that observed for Lyman alpha lines.
