The well-established relations observed between the properties of host galaxies and their nuclear black hole activity suggest the presence of a solid yet still mysterious mechanism that makes BH behavior at nuclear scale impacting the galaxy-scale environment. 
Multi-band observations of AGN-driven outflows support the idea that energy-conserving outflows may induce AGN feedback not only in powerful active galaxies, but also at lower luminosity regime. 
In this context, tracing each phase of the outflow from the X-ray accretion disc winds to the large scale optical and molecular massive outflows offers a tool to understand how the initial energy of the nuclear wind is transferred outward. 
Narrow Line Seyfert 1 Galaxies with their bright X-ray spectra and newly-revealed stratified Ultra Fast Outflows are promising targets where such mechanism can be explored. 
I will present preliminary results on a sample of NLSy1 selected to have powerful X-ray UFOs in XMM-Newton grating spectra, with particular emphasis on the shocked outflow revealed in the multi-band campaign of IRAS17020+4544 (XMM-Newton, LMT, NOEMA Chandra,HST-COS, e-MERLIN, VLBA), and I will discuss the properties of the molecular gas of these NLSy1 studied via mm observations with the IRAM-30m telescope. If time allows, follow-up observations available for some of these sources will be presented too.  

Brief CV of Dr. Anna Lia Longinotti:

Dr. A.L. Longinotti got her Ph.D at Imperial College London in 2006. She worked as a postdoctoral researcher at the European Space Agency and at the MIT-Kavli Institute for Astrophysics and Space Research, where she gained her experience in the field of Active Galactic Nuclei observed by X-ray space observatories. She worked as Community Support Scientist for XMM-Newton and later in 2015 she joined the HAWC  Collaboration (High Altitude Water Cherenkov Observatory). She is currently part of the academic staff of the Institute of Astronomy of UNAM (Universidad Nacional Autónoma de Mexico). Her scientific interests include the multi-frequency properties of AGN, the understanding of the mechanisms of accretion and ejection of matter by black holes, the phenomenon of AGN winds, and their feedback role in galaxy formation and evolution. She has a strong commitment to teaching, training and student tutoring activities.
