Abstract:
We present a host morphological study of 1266 far-infrared galaxies
(FIRGs) and submillimeter galaxies (SMGs) in the Cosmic Evolution
Survey field using the F160W and F814W images obtained by the Hubble
Space Telescope. The FIRGs and SMGs are selected from the Herschel
Multi-tiered Extragalactic Survey and the SCUBA-2 Cosmology Legacy
Survey, respectively. Their precise locations are based on the
interferometry data from the Atacama Large Millimeter/submillimeter
Array and the Very Large Array. These objects are mostly at 0.1≲z≲3.
The SMGs can be regarded as the population at the high-redshift tail
of the FIRGs. Most of our FIRGs/SMGs have a total infrared luminosity
(LIR) in the regimes of luminous and ultraluminous infrared galaxies
(LIRGs, LIR=1011-12L☉; ULIRGs, LIR>1012L☉). The
hosts of the SMG ULIRGs, FIRG ULIRGs, and FIRG LIRGs are of sufficient
numbers to allow for detailed analysis, and they are only modestly
different in their stellar masses. Their morphological types are
predominantly disk galaxies (type D) and irregular/interacting systems
(type Irr/Int). There is a morphological transition at z∼1.25 for the
FIRG ULIRG hosts, above which the Irr/Int galaxies dominate and below
which the D and Irr/Int galaxies have nearly the same contributions.
The SMG ULIRG hosts seem to experience a similar transition. This
suggests a shift in the relative importance of galaxy
mergers/interactions versus secular gas accretions in "normal" disk
galaxies as the possible triggering mechanisms of ULIRGs. The FIRG
LIRG hosts are predominantly D galaxies over z=0.25-1.25, where they
are of sufficient statistics.
Description:
Our samples are based on the FIR and submillimeter data in the field
of COSMOS (Capak+ 2007, II/284 & Scoville+ 2007ApJS..172...38S 2007ApJS..172...38S). The
far-infrared galaxies (FIRGs) were selected using the data from the
Herschel Multi-tiered Extragalactic Survey (HerMES;
Oliver+ 2012, VIII/95), while the submillimeter galaxies (SMGs) were
selected using the data from the S2CLS (Geach+ 2017, J/MNRAS/465/1789)
and the SCUBA2 COSMOS Survey (S2COSMOS; Simpson+ 2019, J/ApJ/880/43).
We obtained their morphological information mainly based on the HST
WFC3 H160 images from the COSMOS-Drift And SHift (COSMOS-DASH)
program (Mowla+ 2019ApJ...880...57M 2019ApJ...880...57M), and in some cases, we also used
the ACS I814 data from the original COSMOS program. To identify the
counterparts of the FIRGs/SMGs on the HST images, we used the
high-resolution interferometry data from the Automated Mining of the
ALMA Archive in the COSMOS Field (A3COSMOS; Liu+ 2019, J/ApJS/244/40),
as well as the deep 3GHz radio data from the COSMOS-VLA program
(Smolcic+ 2017, J/A+A/602/A1). In a few cases, the identification was
also aided by the Ks data from the UltraVISTA program
(McCracken+ 2012, J/A+A/544/A156). See section 2.
We adopt the standard ΛCDM cosmology with ΩM=0.27,
ΩΛ=0.73, and H0=71km/s/Mpc. All magnitudes are in the
AB system.
