SUMMARY:MUSE-AO view of the starburst-AGN connection: NGC 7130
DESCRIPTION:MUSE-AO view of the starburst-AGN connection: NGC 7130\nDr. Joh
 an Knapen\n\nWe present the discovery of a small 0.2'' (60 pc) radius  kin
 ematically decoupled core, as well as an outflow jet, in the  archetypical
  AGN-starburst "composite" galaxy NGC 7130 from integral  field data obtai
 ned with the adaptive optics-assisted MUSE-NFM  instrument on the VLT. Cor
 recting the already good natural seeing at the  time of our science verifi
 cation observations with the four-laser  GALACSI AO system we reach an unp
 recedented spatial resolution of around 0.15''. We confirm the existence o
 f star-forming knots  arranged in an 0.58'' (185 pc) radius ring around th
 e  nucleus, previously observed from UV and optical  Hubble Space  Te
 lescope and CO(6-5) ALMA imaging. We determine the position of the  nucleu
 s as the location of a peak in gas velocity dispersion. A plume of  materi
 al extends towards the NE from the nucleus until at least the  edge of our
  FOV at 2'' (640 pc) radius which we interpret  as an outflow jet originat
 ing in the AGN. The plume is not visible  morphologically, but is clearly 
 characterised in our data by emission  lines ratios characteristic of AGN 
 emission, enhanced gas velocity  dispersion, and distinct non-circular gas
  velocities. Its orientation is  roughly perpendicular to line of nodes of
  the rotating host galaxy  disk. An 0.2''-radius circumnuclear area of pos
 itive and  negative velocities indicates a tiny inner disk, which can only
  be seen  after combining the integral field spectroscopic capabilities of
  MUSE  with adaptive optics.
