• They propose a new empirical color selection technique designed to select massive quiescent galaxies at 3<z<6 using JWST NIRCam imaging data.
• They identified 44 candidate z~3 quiescent galaxies and derive volume density estimates in excellent agreement with existing reports on similar populations in the CEERS field.

The method consists on using empirically-constrained galaxy SED templates to define regions in color planes that seem to be unique of the quiescent galaxy population at z>3
