Abstract:
We investigate the star-forming activity of a sample of infrared
(IR)-bright dust-obscured galaxies (DOGs) that show an extreme red
color in the optical and IR regime, (i-[22])AB>7.0. Combining an
IR-bright DOG sample with the flux at 22µm>3.8mJy discovered by
Toba & Nagao (2016ApJ...820...46T 2016ApJ...820...46T) with the IRAS faint source catalog
version 2 and AKARI far-IR (FIR) all-sky survey bright source catalog
version 2, we selected 109 DOGs with FIR data. For a subsample of
seven IR-bright DOGs with spectroscopic redshifts (0.07<z<1.0) that
were obtained from the literature, we estimated their IR luminosity,
star formation rate (SFR), and stellar mass based on the spectral
energy distribution fitting. We found that (1) the WISE 22µm
luminosity at the observed frame is a good indicator of IR luminosity
for IR-bright DOGs and (2) the contribution of the active galactic
nucleus to IR luminosity increases with IR luminosity. By comparing
the stellar mass and SFR relation for our DOG sample and the
literature, we found that most of the IR-bright DOGs lie significantly
above the main sequence of star-forming galaxies at similar redshift,
indicating that the majority of IRAS- or AKARI-detected IR-bright DOGs
are starburst galaxies.
