Abstract:We present physical properties of radio galaxies (RGs) with f_1.4GHz_>1mJy discovered by Subaru Hyper Suprime-Cam (HSC) and Very Large Array Faint Images of the Radio Sky at Twenty-Centimeters (FIRST) survey. For 1056 FIRST RGs at 0<z<=1.7 with HSC counterparts in about 100deg^2^, we compiled multi-wavelength data of optical, near-infrared (IR), mid-IR, far-IR, and radio (150MHz). We derived their color excess (E(B-V)_*_), stellar mass, star formation rate (SFR), IR luminosity, the ratio of IR and radio luminosity (q_IR_), and radio spectral index ({alpha}_radio_) that are derived from the spectral energy distribution (SED) fitting with CIGALE. We also estimated Eddington ratio based on stellar mass and integration of the

The original sample was drawn from 3579 radio galaxies (RGs) and
quasars in Paper I (Yamashita+ 2018ApJ...866..140Y), who used the
Hyper Suprime-Cam Subaru Strategic Program survey (HSC-SSP;
Aihara+ 2018PASJ...70S...8A) and FIRST (Helfand+ 2015, VIII/92) data.
We utilized the HSC-SSP broadband forced photometry catalogs of the
early data products internally released as S16A, which were obtained
by observations from 2014 March to 2016 January.
The u-band data were taken from the Kilo-Degree Survey (KiDS) DR3 (de
Jong+, 2017, II/347), which is an ESO public survey carried out with
the VLT Survey Telescope (VST) and OmegaCAM camera.
We compiled J, H and Ks-band data from the VISTA Kilo-degree Infrared
Galaxy Survey (VIKING) DR3 (see II/343).
We utilized W1 (3.4um), W2 (4.6um), W3 (12um), and W4 (22um) data
in ALLWISE (Cutri+ 2014, II/328).
We also used FIR data from Heschel/PACS at 100 and 160um and SPIRE at
250, 350, and 500um. We used H-ATLAS DR1 (Valiante+ 2016, J/MNRAS/462/3146)
containing 120230 sources in the galaxy and mass assembly (GAMA) fields.
The radio data were taken from observations with the Giant Metrewave
Radio Telescope (GMRT). We used continuum flux density at 150MHz
(~1.99 m) provided by the Tata Institute of Fundamental Research
(TIFR) GMRT Sky Survey (TGSS) alternative data release (ADR;
Intema+ 2017, J/A+A/598/A78).
