Probing the He ii Reionization ERA via Absorbing C iv Historical Yield (HIERACHY). III. The C iv Absorber Catalog and Initial Results on Cosmic Abundance Evolution at z ≈ 3–5
As part of the HIERACHY program, we collect the high signal-to-noise ratio and high-spectral resolution optical spectra of 25 quasars at z ≈ 4–5 to constrain the C iv evolution at z ≈ 3–5. In this paper, we report a catalog of 626 (1263) C iv absorption systems (components) at z ≈ 3–5 with a 50%...
