The impact of young radio jets traced by cold molecular gas

Abstract Ranging from a few pc to hundreds of kpc in size, radio jets have, during their evolution, an impact on gaseous environment large range scales. While effect larger scales is well established, it now becoming clear that they can also strongly affect the interstellar medium (ISM) inside host galaxy. Particularly important initial phase ( years) evolution jet, when expand into inner Here we report results obtained for representative group young galaxies using cold molecular gas as tracer jet‐ISM interactions. The sensitivity and high spatial resolution ALMA NOEMA are ideal study details this process. In many objects, find massive outflows driven by plasma even low‐power sources. However, observed limited circumnuclear regions only small fraction ISM leaving Beyond region, jet seems change. Fast replaced milder expansion expanding cocoon created interaction, resulting dispersing heating ISM. These findings line with predictions simulations interacting clumpy suggest more complex view AGN than presently implemented cosmological simulations.
