SUMMARY:Connecting X-ray nuclear winds with galaxy-scale ionised outflows 
 in nearby and z~1.5 quasars - Giulia Tozzi

DESCRIPTION:Outflows driven by active galactic nuclei (AGN) are widely acc
 epted to have a key role in shaping the evolution of the host galaxy\, but
  it is still debated how they are accelerated and propagated on galaxy sca
 les. The most promising ‘engines’ of large-scale winds are the X-ray u
 ltra-fast outflows (UFO)\, originating in the AGN nuclear region. In this 
 talk I will present the results from two recent studies about the accelera
 tion mechanism of AGN-driven winds\, aiming to specifically investigate th
 e link between UFOs and the ionised gas phase of large-scale outflows. I w
 ill describe how we have traced the ionised outflows in MUSE and SINFONI o
 bservations of two local Type-1 Seyferts and two quasars at z~1.5 (i.e. cl
 ose to the peak of AGN activity) respectively\, and then compare our measu
 rements with the theoretical predictions on wind propagation of models.  T
 o put our findings in a broader context\, I will finally discuss our resul
 ts along with those of the small sample of well-studied objects\, known to
  host both UFOs and extended outflows\, showing the good agreement of obse
 rvations with models for almost all objects.\n\n
