TL;DR
This study demonstrates that low-luminosity radio jets can drive massive molecular outflows in galaxy centers, influencing galaxy evolution by removing gas and providing a new perspective on AGN feedback mechanisms.
Contribution
It provides the first spatially-resolved evidence linking low-luminosity jets to molecular outflows in galaxy centers, highlighting their role in galaxy evolution.
Findings
Detected a massive molecular outflow coinciding with a low-luminosity jet.
The outflow carries about 75% of the central gas.
Jet power is sufficient to drive the observed outflow.
Abstract
The energy emitted by active galactic nuclei (AGN) may provide a self-regulating process (AGN feedback) that shapes the evolution of galaxies. This is believed to operate along two modes: on galactic scales by clearing the interstellar medium via outflows, and on circumgalactic scales by preventing the cooling and accretion of gas onto the host galaxy. Radio jets associated with radiatively-inefficient AGN are known to contribute to the latter mode of feedback. However, such jets could also play a role on circum-nuclear and galactic scales, blurring the distinction between the two modes. We have discovered a spatially-resolved, massive molecular outflow, carrying of the gas in the central region of the host galaxy of a radiatively-inefficient AGN. The outflow coincides with the radio jet 540 pc offset from the core, unambiguously pointing to the jet as the driver of this…
