Fractions of quiescent galaxies evolution

Using the UltraVISTA DR1 and 3D-HST catalogs, we construct a stellar-mass-complete sample, unique for its combination of surveyed volume and depth, to study the evolution of the fractions of quiescent galaxies, moderately unobscured star-forming galaxies, and dusty star-forming galaxies as a function of stellar mass over the redshift interval 0.2<=z<=3.0. We show that the role of dusty star-forming galaxies within the overall galaxy population becomes more important with increasing stellar mass and grows rapidly with increasing redshift.

Specifically, dusty star-forming galaxies dominate the galaxy population with log(M_star_/M_{sun}_)>~10.3 at z>~2. The ratio of dusty and non-dusty star-forming galaxies as a function of stellar mass changes little with redshift. Dusty star-forming galaxies dominate the star-forming population at log(M_star_/M_{sun}_)>~10.0-10.5, being a factor of ~3-5 more common, while unobscured star-forming galaxies dominate at log(M_star_/M_{sun}_)<~10.
