Winding Back the Clock: Recent Star Formation Histories of Massive Quiescent Galaxies Are Consistent with Their Rapid Number Density Evolution since z ∼ 7

Massive quiescent galaxies have been identified out to z  ∼ 7 in early JWST data, substantially exceeding (≳1 dex at z  > 4) the number densities from most theoretical predictions. We investigate whether the number densities implied by the star formation histories (SFHs) of quiescent galaxies at 2 <...
