Tracing Radio Emission in SUBWAYS AGN: Unveiling the Role of Winds

AGN are among the most energetic objects in the Universe. While a minority is classified as Radio Loud (RL), with radio emission dominated by synchrotron from powerful jets, most are Radio Quiet (RQ), where radio emission arises from various processes, including AGN-driven winds, SF regions, weak jets, and coronal activity. Disentangling these mechanisms requires spectral and morphological analysis, crucial for understanding AGN feedback and galaxy evolution. To investigate this, I conducted a detailed radio study of the SUBWAYS RQ AGN, a sample of 21 X-ray-selected sources (z = 0.1–0.5) optimized for UFO detection. I explored their radio properties and built their SEDs by combining proprietary JVLA data (1.5 and 6 GHz) with publicly available images from LoTSS, TGSS, RACS, FIRST, and VLASS. My analysis examined the role of the different emission mechanisms, focusing on shocks driven by quasar winds or jets. By combining radio spectral indices, luminosities, and morphologies with multi-wavelength properties (e.g., SFR, X-ray luminosity, and wind parameters), I identified sources with SF-like signatures, while others displayed AGN-driven features, including wind-ISM interactions. Notably, nine sources exhibit extended radio structures (tens of kpc), likely from jets or winds, and one is a giant radio galaxy reaching Mpc scales. Interestingly, all but one UFO host show extended radio emission, suggesting a link between nuclear and large-scale radio outflows. These findings offer new insights into the origin of radio emission in RQ AGN, impacting our understanding of AGN feedback and galaxy evolution, and laying the groundwork for future studies in the SKAO era.
