The origin of the radio jets in the young radio galaxy 4C 52.37
Compact radio galaxies provide an exciting window into the evolution of active galactic nuclei (AGN) and the interaction between the radio jets and the interstellar medium because the radio jets are entirely contained within the host galaxy extending only a few parsecs to kiloparsecs. They are considered to be young AGN that might evolve into large (up to a few Megaparsec) radio galaxies over time. Due to their size and distance, very long baseline interferometry (VLBI) is generally the only way to resolve these systems. A particularly intriguing young radio galaxy is 4C52.37. In a previous VLBI study, we have located the massive outflow of neutral atomic hydrogen (HI) towards the central 100 parsec of the radio source. However, the source has not been studied in detail so far preventing us from properly assessing where the HI outflow is located with respect to the origin of the jets. Now, we have the opportunity to obtain this vital information by constraining the jet geometry through detailed multi-frequency VLBI observations. Therefore, we propose high-sensitivity, phase-referencing EVN observations at 2.3, 5.0, 8.4 and 22.2 GHz.
