4MOST ChANGES: Catalog of high-redshift quasar candidates (4.5 < z < 7) selected via spectral-energy-distribution fitting

Context. The identification of high-redshift quasars (z > 4.5) is critical for studying the early Universe, supermassive-black-hole growth, and cosmic reionization. Most known high-redshift quasars are located in the northern hemisphere, leaving the southern sky largely unexplored. Aims. As part of...
