Aligned metal absorbers and the ultraviolet background at the end of reionization

Caitlin Doughty, Kristian Finlator, Benjamin D. Oppenheimer +2

We use observations of spatially-aligned C II, C IV, Si II, Si IV, and O I absorbers to probe the slope and intensity of the ultraviolet background (UVB) at $z\sim 6$. We accompli…
