DESCRIPTION:Galactic-scale outflows are one of the major feedback mechanis
 ms regulating the growth of galaxies. Despite the import role outflows pla
 y in galaxy evolution\, the occurrence and properties of outflows are not 
 well constrained yet. By taking advantage of the integral\nfield spectrosc
 opy (IFS) technique we can unambiguously identify wind galaxies by investi
 gating the absorption and emission line kinematics. The first part of this
  talk will present VIMOS-observations of neutral\noutflows in nearby extre
 me starbursts (such as [U]LIRGs) via the optical IFS of NaD (λλ5890\, 58
 96). The neutral gas velocity fields are generally dominated by non-circul
 ar motions\, and in nearly half of the\nsample (22/51) we have revealed an
  outflow signature. The quantitative analysis of the outflow feedback and 
 kinematics suggest that it is relevant for both the quenching of star form
 ation and for the recycling of gas and metals within the galaxy. The secon
 d part of this\ntalk is dedicated to the study of the [OIII]λ5007 line em
 ission\, which is a good tracer of outflows and ionized gas dynamics in th
 e narrow-line regions of AGN\, in a sample of high redshift quasars. More 
 specifically\, VLT-SINFONI near-IR integral field spectra of five\nquasar 
 at redshift z=2.4 are presented and discussed. The kinematical analysis of
  the [OIII] line shows complex gas kinematics in a region of several kpc f
 rom the location of the AGN\, with blueshifted velocities of a few hundred
 s of km/s and line widths up to 1500 km/s.\n[OIII] emission likely traces 
 a massive outflow with a conical morphology. Meanwhile\, Hα emission\, tr
 acing star formation\, is strongly suppressed in the outflows regions. The
 se observations suggests a clear evidence of AGN negative feedback.\n
