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(Mstar/M☉)≳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(Mstar/M☉)≳10.0-10.5,
being a factor of ∼3-5 more common, while unobscured star-forming
galaxies dominate at log(Mstar/M☉)≲10. At
log(Mstar/M☉)>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
1.62deg2 and the 3D-HST (Skelton+ 2014, J/ApJS/214/24; Momcheva+
2016ApJS..225...27M 2016ApJS..225...27M) covering 900arcmin2, catalogs.
