Dust obscured galaxies (DOGs) are expected to have a rapidly growing SMBH and starburst activity, and some of them might reach super Eddington accretion to the SMBH. Motivated by the theoretical suggestion that the super-Eddington phase efficiently produces outflow and jets bright in radio bands, we cross-matched HSC-WISE DOGs with VLA/FIRST radio catalog. We found 29 radio-loud DOGs out of ~1300 DOGs. In this study, we have conducted the SED fitting using HSC photo-z (DNNz) and CIGALE code, which enable us to assess the AGN bolometric luminosity, stellar-mass based BH mass, and then Eddington ratio. Using scaling relation (Kormendy & Ho 2013), 30% of the radio-loud DOGs appear to exceed the Eddington limit, which is much higher than the VLA/FIRST undetected DOGs of 7% or SDSS quasar of 0.1% at z~1. In addition, one radio-loud DOG with SDSS optical spectra exceeds the Eddington limit. These results suggest that we efficiently obtain super-Eddington systems in dust-obscured phase using DOGs criteria with bright radio emission.
