Abstract:
We analyze the far-infrared (FIR) properties of ∼5000 star-forming
galaxies at z<4.5, drawn from the deepest, super-deblended catalogs in
the GOODS-N and COSMOS fields. We develop a novel panchromatic
spectral energy distribution fitting algorithm, Stardust, that models
the emission from stars, active galactic nuclei (AGNs), and infrared
dust emission, without relying on energy balance assumptions. Our code
provides robust estimates of the UV- optical and FIR physical
parameters, such as the stellar mass (M*), dust mass (Mdust), infrared
luminosities (LIR) arising from AGN and star formation activity, and
the average intensity of the interstellar radiation field ().
Through a set of simulations we quantify the completeness of our data
in terms of Mdust, LIR, and and subsequently characterize the
distribution and evolution of these parameters with redshift. We focus
on the dust-to-stellar mass ratio (fdust), which we parameterize as a
function of cosmic age, stellar mass, and specific star formation
rate. The fdust is found to increase by a factor of 10 from z=0 to z=2
and appears to remain flat at higher z, mirroring the evolution of the
gas fraction. We also find a growing fraction of warm to cold dust
with increasing distance from the main sequence, indicative of more
intense interstellar radiation fields, higher star formation
efficiencies, and more compact star-forming regions for starburst
galaxies. Finally, we construct the dust mass functions (DMFs) of
star-forming galaxies up to z=1 by transforming the stellar mass
function to DMF through the scaling relations derived here. The
evolution of fdust and the recovered DMFs are in good agreement with
the theoretical predictions of the Horizon-AGN and IllustrisTNG
simulations.
