Abstract We present an analysis of the quenching star formation in massive galaxies ( M * > 10 9.5 ⊙ ) within first 0.5–3 Gyr Universe’s history utilizing JWST-CEERS data. utilize a combination advanced statistical methods to accurately constrain intrinsic dependence multidimensional and intercorrelated parameter space. Specifically, we apply random forest classification, area statistics, partial correlation First, identify key testable predictions from two state-of-the-art cosmological simulations IllustrisTNG EAGLE ). Both predict that should be regulated by supermassive black hole mass early Universe. Furthermore, both stellar potential ϕ as optimal proxy for photometric In observations, where have no direct constraints on masses, find is most predictive galaxy at all epochs z = 0–8, exactly predicted this sample.

Collectively, these results strongly imply stable mechanism operating throughout cosmic history, which closely connected central gravitational galaxies. This connection explained models via holes forming growing deep wells, subsequently through mix ejective preventative active galactic nucleus feedback.
