The origin of radio emission in radio-quiet AGN remains a central debate regarding the nature of accretion and feedback around supermassive black holes. While this emission is often attributed to star formation or diffuse outflows, current evidence increasingly points toward a compact jet base or a magnetized corona tied to the sub-parsec accretion engine. The most definitive diagnostic for...

The classical Fanaroff-Riley (FR) classification of radio galaxies is primarily based on powerful and extended FRI and FRII sources. However, more sensitive radio and optical surveys have revealed a large population of compact radio galaxies in the local Universe, known as FR0s, which outnumber FRIs by a factor of 5. Despite these populations share many properties, FRIs develop powerful...

51. Resolved Radio Emission from a Radio-loud, Super-Eddington Quasar at z=3.4

AGN in the local universe exhibit an inverse correlation between radio-loudness and Eddington ratio. Furthermore, the radio emission in local radio-loud AGN is typically dominated by a large scale jet. I will present the results of a very long baseline interferometry study of eROSITA Final Equatorial Depth Survey J084222.9+001000, a super-Eddington ($\lambda_{\rm Edd, UV}$ = 1.4 and...
