DESI survey of S IV absorption outflows in quasars: Contribution to AGN feedback and comparison with [O III] emission outflows Open
Aims. Quasar outflows play a crucial role in the evolution of their host galaxies through various feedback processes. This effect is thought to be particularly important when the Universe was only 2–3 billion years old, during the period k…
