Abstract:
We present a new catalog of 118 ultraluminous infrared galaxies
(ULIRGs) and one hyperluminous infrared galaxy (HLIRG) by
cross-matching the AKARI all-sky survey with the Sloan Digital Sky
Survey Data Release 10 (SDSS DR10) and the final data release of the
Two-Degree Field Galaxy Redshift Survey. Forty of the ULIRGs and one
HLIRG are new identifications. We find that ULIRGs are interacting
pair galaxies or ongoing or postmergers. This is consistent with the
widely accepted view: ULIRGs are major mergers of disk galaxies. We
confirm the previously known positive trend between the active
galactic nucleus fraction and infrared luminosity. We show that ULIRGs
have a large offset from the main sequence up to z ∼ 1; their offset
from the z ∼ 2 "main sequence" is relatively smaller. We find a result
consistent with the previous studies showing that, compared to local
star-forming SDSS galaxies of similar mass, local ULIRGs have lower
oxygen abundances. We demonstrate for the first time that ULIRGs
follow the fundamental metallicity relation (FMR). The scatter of
ULIRGs around the FMR (0.09 dex-0.5 dex) is comparable to the scatter
of z ∼ 2-3 galaxies. We provide the largest local (0.050 <z < 0.487)
ULIRG catalog with stellar masses, star-formation rates, gas
metallicities, and optical colors.

Note (1): LIR is the total IR luminosity between 8 and 1000µm measured from
the SEDs fitted to the AKARI fluxes at 65, 90, 140, and 160µm.
Note (2): The AKARI flux density and the associated uncertainties are adopted
from Yamamura et al. (2010, Cat. II/298). For the cases for which the
flux uncertainties are not available, we adopt 25% of the measured
flux as the uncertainty.
Note (3): The interaction classes (IC) listed in this table are based on
combined gri SDSS images; "..." entries in the table indicate the
lack of an SDSS image. The classification scheme used (see Section 3.2
of the paper and also Veilleux et al. 2002, Cat. J/ApJS/143/315) is
described as follows:
I = first approach. Separated galaxies with no signs of interaction
or merging.
II = first contact. Overlapped disks without interaction signs.
III = premergers. Two nuclei separated by more than 10 kpc (a; wide binary)
or less than 10 kpc (b; close binary), with interaction signs.
Tp1 = interacting triplet system.
IV = merger. One nucleus with prominent tidal features.
V = old merger. Disturbed central morphology without clear tidal tail
signs.
NI = noninteracting. Isolated single galaxy, no signs of disturbed
morphology.
Note (4): References on IC, defined as follows:
1 = Veilleux et al. (2002, Cat. J/ApJS/143/315);
2 = Hwang et al. (2007, Cat. J/MNRAS/375/115);
3 = this work.
Note (5): Superposition of other sources in the field, defined as follows:
A = star;
B = galaxy.
Note (6): Classifications based on optical spectra. For the sources that are in
the SDSS DR10 emissionlinesPort catalog (Thomas et al.
2013MNRAS.431.1383T 2013MNRAS.431.1383T), we adopt the given BPT classifications: star
forming, composite, LINER, and Seyfert. In the case of quasars (QSO),
we adopt the "spectrotype" classification from the galSpecInfo catalog
(see Richards et al. 2002AJ....123.2945R 2002AJ....123.2945R, for the details of SDSS
spectroscopic target selection). The classifications marked with a
star are based on our BPT classification based on the emission-line
fluxes adopted from the SDSS catalog galSpecLine (Tremonti et al.
2004ApJ...613..898T 2004ApJ...613..898T; Brinchmann et al. 2004MNRAS.351.1151B 2004MNRAS.351.1151B).
