The Evolution of the Fractions of Quiescent and Star-forming Galaxies as
  a Function of Stellar Mass Since z=3: Increasing Importance of Massive, Dusty
  Star-forming Galaxies in the Early Universe
  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 $0.2 \le z \le 3.0$. 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 $\log{(M_{\rm star}/M_{\odot})} \gtrsim
10.3$ at $z\gtrsim2$. 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 $\log{(M_{\rm
star}/M_{\odot})} \gtrsim 10.0-10.5$, being a factor of $\sim$3-5 more common,
while unobscured star-forming galaxies dominate at $\log{(M_{\rm
star}/M_{\odot})} \lesssim 10$. At $\log{(M_{\rm star}/M_{\odot})} > 10.5$, 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).
