Abstract:
We report on 167 infrared (IR) galaxies selected by AKARI and IRAS and
detected in the Atacama Cosmology Telescope (ACT) Data Release 5 (DR5)
sky maps at the 98, 150, and 220GHz frequency bands. Of these
detections, 134 (80%) of the millimeter counterparts are first-time
identifications with ACT. We expand the previous ACT extragalactic
source catalogs, by including new 98GHz detections and measurements
from ACT DR5. We also report flux density measurements at the 98, 150,
and 220GHz frequency bands. We compute α98-150, α98-220,
and α150-220 millimeter-wave spectral indices and far-IR to
millimeter-wave spectral indices between 90µm and 98, 150, and
220GHz. We specify the galaxy type, based on α150-220. We
combine publicly available multiwavelength data-including ultraviolet,
optical, near-IR, mid-IR, far-IR, and the millimeter measurements
obtained in this work-and perform spectral energy distribution (SED)
fitting with CIGALE. With the radio emission decomposition advantage
of CIGALE V2022.0, we identify the origins of the millimeter emissions
for 69 galaxies in our sample. Our analysis also shows that millimeter
data alone indicates the need for a radio synchrotron component in the
SEDs that are produced by active galactic nuclei (AGNs) and/or star
formation. We present SEDs and measured physical properties of these
galaxies, such as the dust luminosity, AGN luminosity, the total IR
luminosity, and the ratio of the IR and radio luminosity. We quantify
the relationships between the total IR luminosity and the
millimeter-band luminosities, which can be used in the absence of SED
analysis.
