Discrepancies between JWST Observations and Simulations of Quenched Massive Galaxies at z > 3: A Comparative Study with IllustrisTNG and ASTRID

Recent JWST observations have uncovered an unexpectedly large population of massive quiescent galaxies at z  > 3. Using the cosmological simulations IllustrisTNG and ASTRID , we identify analogous galaxies and investigate their abundance, formation, quenching mechanisms, and post-quenching evolut...
