Abstract : We study the difference between host galaxy properties of radio loud (RL) and radio quiet (RQ) quasars using the sample from Shen et al. (2011). We use the state-of-the-art spectral energy distribution (SED) modeling code X-CIGALE to model the SEDs of quasar host galaxies. From a sample of 31 RL quasars and 14 RQ quasars, we obtain distributions of average star formation rates over 10 Myr, e-folding times of main stellar population models, ages of the main stellar populations, total stellar masses, and dust luminosities; and observe their dependencies on radio-loudness of the central quasars. We find that the total stellar masses are very similar for both RL and RQ quasars, as is the luminosity absorbed by the dust; whereas average star formation rate (SFR) and e-folding times are higher for RL quasars, and the main stellar population age is higher for RQ quasars, on an average.
