Appendix B from "Supermassive Black Hole Winds in X-rays: SUBWAYS IV. Tracing radio emission and unveiling the role of winds". It contains the Spectral Energy Distributions (SEDs) of all the targets involved in the study and their radio and optical images. Paper Abstract: Context. Most Active Galactic Nuclei (AGN) are Radio Quiet (RQ), with radio emission that may arise from star-formation activity, AGN-drivenwinds, weak jets, and coronal activity. Disentangling these mechanisms is challenging and requires detailed multi-wavelength investigation, but itis crucial for quantifying AGN feedback in galaxy evolution.Aims. We present a detailed radio investigation of 22 X-ray selected AGN in the Supermassive Black Hole Winds in X-Rays (SUBWAYS) sample(Lbol ≃ 1044.9−46.3 erg/s, z=0.1-0.5), selected to systematically search for Ultra-Fast Outflows (UFOs). UFOs are detected in ∼ 30% of the targets,with measured velocities and kinetic luminosities, making the sample particularly well-suited for investigating the role and signatures of multi-scale outflows at different frequencies.Methods. We build the radio Spectral Energy Distribution of the sources complementing our proprietary data, collected with the JVLA at 1.5 and6 GHz, with images from LoTSS (145 MHz) and other publicly available radio surveys between 150 and 1400 MHz.We investigate the role and occurrence of the aforementioned mechanisms, with particular interest in outflows and their possible relation withUFOs. To achieve this, we combined information on spectral indices, luminosities, and morphologies of the radio emission with properties derivedin other wavebands, such as the Star Formation Rate, the X-ray luminosity, the Eddington ratio or the UFO kinetic luminosity.Results. All the sources are detected and are mostly consistent with RQ AGN. For ∼ 80% of the sources the data suggest the presence of anoutflow (wind or weak jet). Interestingly, our results indicate that AGN with UFOs tend to have larger radio extension and a steep radio spectrumconsistent with outflows. Moreover, the radio emission of the 6 UFO hosts is consistent with predictions from wind-driven shock models, possiblyindicating a direct connection between the two phases. Alternatively, this may simply reflect physical conditions that favour the production of bothphenomena.
