AbstractWe investigate two classes of conditions for galaxy quenching at 0.5 1010M⊙) have much higher stellar mass surface densities within the central 1 kpc (∑1) and smaller sizes than star-forming galaxies in the same stellar mass range. In addition, the quiescent fractions significantly increase with the increase of ∑1 regardless of whether galaxies are centrals or satellites. In contrast, we find that the overall lower-mass quiescent galaxies (M? <~ 1010M⊙) have slightly higher ∑1 and comparable sizes compared to starforming galaxies of the same mass and at the same redshift. At z < 1.5, satellites have higher halo masses and larger quiescent fractions than those of centrals at a given ∑1 (stellar mass). Our findings indicate that the significant growth of the galaxy cores is closely related to the quenching of massive galaxies since z ~ 2.5, while the environmental effect plays an important role in the quenching of low-mass galaxies at z ? 1.5.
