Abstract:
The James Webb Space Telescope (JWST) enables the identification of
quiescent galaxies (QGs) out to early epochs, offering a
transformative view of their evolution. However, photometric selection
of quiescent galaxy candidates (QGCs) and the derivation of their key
physical quantities, such as stellar masses (M*) and dust attenuation,
remain highly sensitive to the assumed star-formation histories
(SFHs), where dust-age degeneracies and modelling choices remain a
major source of uncertainty. We aim to quantify how the inclusion of
JWST/MIRI data and different SFH models impacts the selection and
characterisation of QGCs. We test the robustness of the physical
properties inferred from the spectral energy distribution (SED)
fitting, such as M*, age, star formation rate (SFR), and dust
attenuation (AV), and study how they impact the quiescence criteria of
the galaxies across cosmic time. We perform SED fitting for ∼13000
galaxies at z≤6 from the CEERS/MIRI fields with ≤20 optical-mid
infrared (MIR) broadband coverage. We implement three SFH
prescriptions: a flexible delayed, non-parametric, and an extended
regulator model. For each SFH, we compare results obtained with and
without MIRI photometry and dust emission models. We evaluate the
impact of these configurations on both the number of QGCs, selected
based on rest UVJ colours, sSFR and main-sequence offset, and on their
key physical properties such as M*, AV, and stellar ages. The number
of selected QGCs varies significantly with the choice of SFH ranging
from 70 to 100, out of a mass-complete sample of ∼5000 galaxies,
depending on the model. This number increases to 103-180 when MIRI
data are included, driven by improved constraints on both dust
attenuation and M*. We find a strong correlation between AV and M* of
QGCs at z≤2.5, with massive galaxies (M*∼1011M☉) being ∼1.5-4
times more attenuated than low-mass galaxies (M*∼109M☉).
Regardless of the SFH, ∼13% of QGCs exhibit significant attenuation
(AV>0.5) in support of recent JWST results on dust-rich QGs.
Description:
The catalogue contains main physical properties for 12939 galaxies
within MIRI footprint of CEERS field. We perform spectral energy
distribution (SED) modelling with CIGALE v2022.01. Each galaxy was
fitted 6 times. We tested three different star formation histories
(SFHs; DelayedBQ, Nonparametric and Regulator). Each SFH was used
twice: 1) with use of MIRI data; 2) without using MIRI data. We report
all 6 values in the table. We note that for each parameter CIGALE
makes a probability distribution function (PDF) analysis, and the
output value is the likelihood-weighted mean of the PDF (and
consequently, the associated error is likelihood-weighted standard
deviation).
