Because supermassive black holes (SMBHs) in IR-bright DOGs are expected to be rapidly growing in the major-merger scenario, they provide useful clues for understanding the coevolution of SMBHs and their host galaxies. However, the optical properties of IR-bright DOGs remain unclear because the optical emission of a DOG is very faint. By combining ~105deg^2^ images of the optical, near-IR, and mid-IR data obtained from the Subaru Hyper Suprime-Cam (HSC) survey, the VISTA VIKING survey, and the Wide-field Infrared Survey Explorer all-sky survey, respectively, 571 IR-bright DOGs were selected. We found that IR-bright DOGs show a redder (g-z)_AB_ color than do other populations of dusty galaxies, such as ultraluminous IR galaxies (ULIRGs) at a similar redshift, with a significantly large dispersion. Among the selected DOGs, star formation (SF)-dominated DOGs show a relatively red color, while active galactic nucleus (AGN)-dominated DOGs show a rather blue color in optical. This result is consistent with the idea that the relative AGN contribution in the optical emission becomes more significant at a later stage in the major-merger scenario. We discovered eight IR-bright DOGs showing a significant blue excess in blue HSC bands. This blue excess can be interpreted as a leaked AGN emission that is either a directly leaking or a scattered AGN emission, as proposed for some blue-excess Hot DOGs in earlier studies.2019ApJ...876..132Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/876/132CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/subaru : Log of Subaru Prime Focus Camera Exposures (ADAC NAOJ, 2007)III/88 : Stellar Spectrophotometric Atlas (Gunn+ 1983)II/328 : AllWISE Data Release (Cutri+ 2013)II/326 : Revised SWIRE photometric redshifts (Rowan-Robinson+, 2013)II/343 : VIKING catalogue data release 2 (Edge+, 2016)VII/279 : SDSS quasar catalog: twelfth data release (Paris+, 2017)J/PASP/110/863 : Stellar Spectral Flux Library: 1150-25000{AA} (Pickles 1998)J/AJ/131/2766 : Quasar luminosity function from SDSS-DR3 (Richards+, 2006)J/ApJ/663/81 : SED of hard X-ray selected AGN in XMDS (Polletta+, 2007)J/MNRAS/413/971 : Galaxy And Mass Assembly (GAMA) DR1 (Driver+, 2011)J/ApJ/744/150 : Dust-obscured galaxies (DOGs) at z=~2 (Bussmann+, 2012)J/AJ/143/125 : SED of 113 dust-obscured galaxies at z~2 (Melbourne+, 2012)J/ApJ/750/99 : The Pan-STARRS1 photometric system (Tonry+, 2012)J/ApJ/797/54 : ULIRGs in the AKARI all-sky survey (Kilerci Eser+, 2014)J/ApJ/840/21 : IR-bright dust-obscured galaxies (DOGs) (Toba+, 2017)J/ApJ/850/140 : SDSS spectral analysis of IR-bright DOGs (Toba+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/876/132https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/876/132http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/876/132https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/876/132https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/876/132http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/876/132GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/876/132/table11 (Catalog of dust-obscured galaxies (DOGs) in this study)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/876/132/table11?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/876/132/table11?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/876/132/table11?GETtext/xml+votable180.050000true34.19785-4.226280.0055555555555555565/1024 4422 4423 5461 5463 5468 6479 6483 6484 6485 6486 6488 6489 6490 6501 6512 6570 6740 6824 6826 6827 6/4100 4101 4102 4104 8194 17677 17682 17683 17686 17712 17713 17717 21839 21843 21848 21849 21851 21861 21876 21878 21881 25591 25595 25597 25598 25599 25915 25927 25948 25949 25950 25965 25966 25967 25968 25969 25970 26000 26001 26003 26009 26012 26013 26052 26056 26274 26275 26286 26964 26965 26966 26968 26969 26971 26972 26974 27275 27276 27278 27279 27302 27303 27312 27314 27315 27320 27321 27322 27648 27649 27650 40957 40959 45051 450558.157980699529898e-21 4.963257411639215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/876/132?format=asciiOpticalInfrareddefaultJ/ApJ/876/132/table11Catalog of dust-obscured galaxies (DOGs) in this studyrecnoRecord number assigned by the VizieR team.
