Abstract

Abstract We investigate the correlation between ionized-gas outflows, jets, and star formation in a sample of 42 local type-I active galactic nuclei (AGNs) exhibiting significant [O III ] outflows. This study uses both new submillimeter observations and archival data from the James Clerk Maxwell Telescope. Our analysis, which includes a correction for jet emission in the submillimeter bands, fitting spectral energy distribution, and analyzing spectra, enables us to derive star formation rates (SFRs) through various methods. By comparing radio power and SFRs, we select a subsample of jetted AGNs of which radio emission is mostly from the jets. We find that jetted AGNs predominantly lie above the main sequence of star-forming galaxies, suggesting a correlation between jet activity and star formation. By comparing dust extinction, we demonstrate that jetted AGNs do not have more dust, which is the fuel of both star formation and AGN activity. Therefore, this correlation is more likely to arise from AGN feedback. We also find that the Eddington ratio does not impact the specific SFRs (sSFRs) of our sample. Additionally, for jetted AGNs, stronger radio emission corresponds to higher sSFRs, suggesting that jet emission may promote star formation, i.e., positive feedback. Our results not only shed light on the feedback mechanisms of AGNs but also underscore the complex interplay between black hole activity and star formation in galaxy evolution.
