text: "Aims. This paper utilises the James Webb Space Telescope (JWST) Mid-Infrared
Instrument (MIRI) to extend the observational studies of dust and polycyclic aromatic
hydrocarbon (PAH) emission to a new mass and star formation rate (SFR) parameter
space beyond our local Universe. The combination of fully sampled spectral energy
distributions (SEDs) with multiple mid-infrared (mid-IR) bands and the unprecedented
sensitivity of MIRI allows us to investigate dust obscuration and PAH behaviour
from z = 0.7 up to z = 2 in typical main-sequence galaxies. Our focus is on constraining
the evolution of PAH strength and the dust-obscured luminosity fraction before
and during cosmic noon, the epoch of peak star formation activity in the Universe.\r\n\r\nMethods.
In this study, we utilise MIRI multi-band imaging data from the SMILES survey
(5 to 25 μm), complemented with NIRCam photometry from the JADES survey (1 to
5 μm), available HST photometry (0.4 to 0.9 μm), and spectroscopic redshifts from
the FRESCO and JADES surveys in GOODS-S for 443 star-forming (without dominant
active galactic nucleus (AGN)) galaxies at z = 0.7 − 2.0. This redshift range
was chosen to ensure that the MIRI data cover mid-IR dust emission. Our methodology
involved employing ultraviolet (UV) to IR energy balance SED fitting to robustly
constrain the fraction of dust mass in PAHs and dust-obscured luminosity. Additionally,
we inferred dust sizes from MIRI 15 μm imaging data, enhancing our understanding
of the physical characteristics of dust within these galaxies.\r\n\r\nResults.
We find a strong correlation between the fraction of dust in PAHs (PAH fraction,
qPAH) with stellar mass. Moreover, the sub-sample with robust qPAH measurements
(N = 216) shows a similar behaviour between qPAH and gas-phase metallicity to
that at z ∼ 0, suggesting a universal relation: qPAH is constant (∼3.4%) above
a metallicity of Z ∼ 0.5 Z⊙ and decreases to < 1% at metallicities ≲0.3 Z⊙. This
indicates that metallicity is a good indicator of the interstellar medium properties
that affect the balance between the formation and destruction of PAHs. The lack
of a redshift evolution from z ∼ 0 − 2 also implies that above Z ∼ 0.5 Z⊙ the
PAH emission effectively traces obscured luminosity and the previous locally calibrated
PAH-SFR calibrations remain applicable in this metallicity regime. We observe
a strong correlation between the obscured UV luminosity fraction (ratio of obscured
to total luminosity) and stellar mass. Above the stellar mass of M* > 5 × 109
M⊙, on average, more than half of the emitted luminosity is obscured, while there
exists a non-negligible population of lower-mass galaxies with > 50% obscured
fractions. At a fixed mass, the obscured fraction correlates with SFR surface
density. This is a result of higher dust covering fractions in galaxies with more
compact star-forming regions. Similarly, galaxies with high IRX (IR to UV luminosity)
at a given mass or UV continuum slope (β) tend to have higher ΣSFR and shallower
attenuation curves, owing to their higher effective dust optical depths and more
compact star-forming regions."
