Abstract:
We present physical properties of luminous radio galaxies (RGs) at 0 < z < 1.7 discovered by Subaru Hyper Suprime-Cam (HSC) and VLA FIRST survey. For 1056 FIRST RGs with HSC counterparts in about 100 deg^2, we compiled multi-wavelength data of optical, near-infrared (IR), mid-IR, far-IR, and radio (150 MHz). We derived their color excess (E(B-V*)), stellar mass, star formation rate (SFR), IR luminosity, the ratio of IR and radio luminosity (qIR), and radio spectral index (alpha_radio) that are derived from the SED fitting with CIGALE. The physical properties of a fraction of RGs in our sample seem to differ from a classical view of RGs with massive stellar mass, low SFR, and low Eddington ratio, demonstrating that our RG survey with HSC and FIRST provides us curious RGs among entire RG population (Toba et al. 2019, ApJS, re-submitted).
