| Abstract: |
Our deep molecular line images of nearby starburst galaxies and AGNs
exhibit molecular outflows in most galaxies, and have revealed that
the molecular outflows co-exist with outflows or jets seen in other
wavelengths.
In case of starbursts, X-ray outflows have higher energy and pressure
than those of molecular outflows, suggesting that plasma outflows are
blowing the molecular gas away from starburst
regions, which suggests a strong negative feedback.
On the other hand, current starburst regions in M82 can be seen at
the inner edge of an expanding molecular bubble, suggesting a
positive feedback.
In case of AGNs, jets seem to entrain the surrounding molecular gas
away from the AGNs, suggesting a negative feedback. |
