In the most extreme systems, supermassive black holes (SMBHs) can accrete near or above the Eddington limit, representing a complex, yet poorly understood accretion state. At high accretion rates, theory predicts much energy can be carried away from the inner regions of active galactic nuclei (AGNs) by powerful winds and jets. To further investigate the accretion process and associated feedback mechanisms in these extreme environments, we propose to observe IRAS 04416+1215, a hyper-Eddington AGN with the highest known Eddington ratio of 472 in the local universe and multiple absorption wind structures, which provides a unique environment to study jet and wind physics under extreme accretion conditions. The observation will be conducted in L- and C-band, with a total requested observation time of 12 hours. Through this observation, we will be able to determine the inner structure of IRAS 04416+1215, reveal the origin of its radio emission and gain insights into the outflow launching mechanism. Furthermore, this observation will enable us to examine whether the radio jet is suppressed in such a high accretion rate and explore the relationships between outflows and accretion properties.
