DESCRIPTION:Speaker: Prof. Rogemar Riffel (UFSM\, Brazil)\nTitle: BAH - Bl
 owing star formation away in Active galactic nuclei Hosts\nAbstract: In th
 is talk\, I will present recent results from the Blowing star formation aw
 ay (BAH) project\, which aims to explore the interplay between AGN feeding
  and feedback through multiwavelength observations of nearby AGN hosts wit
 h strong H2 emission in the mid-infrared. JWST MIRI MRS and NIRSpec IFU ob
 servations of three BAH galaxies reveal molecular and ionised gas outflows
  and indicate that shocks are the dominant mechanism exciting the warm H2.
  These results are complemented by the analysis of a larger sample of ~60 
 nearby galaxies using archival MIRI MRS observations. AGNs exhibit broader
  emission lines than star-forming galaxies (SFGs)\, with the largest veloc
 ity dispersions found in radio-strong AGNs. H2 is generally less turbulent
  than the ionised gas\, while coronal-line emitting gas exhibits even high
 er velocity dispersions. Taken together\, these results point to shock hea
 ting as an\nimportant mechanism shaping the kinematics and excitation of t
 he ISM. This shock-induced gas heating may represent an important mechanis
 m of AGN feedback\, preventing the gas from cooling and forming new stars.
