Abstract:
    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. At
    log(M_star_/M_{sun}_)>10.5, red galaxies dominate the galaxy
    population at all redshift z<3, either because they are quiescent (at
    late times) or dusty star-forming (in the early universe).

Description:
    We used the UltraVISTA DR1 (Muzzin+ 2013, J/ApJS/206/8) covering
    1.62deg^2^ and the 3D-HST (Skelton+ 2014, J/ApJS/214/24; Momcheva+
    2016ApJS..225...27M) covering 900arcmin^2^, catalogs.
