DESCRIPTION:LBQS 0302-0019 is a blue QSO at z ∼ 3.3\, hosting powerful o
 utflows\, and residing in a complex environment consisting of an obscured 
 AGN candidate and multiple companions\, all within 30 kpc in projection. I
 n this talk I will present the JWST/NIRSpec IFS observations of this compl
 ex system. We developed a procedure to correct for the spurious oscillatio
 ns in NIRSpec single-spaxel spectra\, due to the spatial under-sampling of
  the point spread function. We performed a quasar-host decomposition with 
 the QDeblend3D tools\, and used multi-component kinematic decomposition of
  the optical emission line profiles to infer the physical properties of th
 e emitting gas. We identified i) a low-velocity component possibly tracing
  a warm rotating disk\; ii) a powerful ionised outflow\, with an outflow m
 ass rate of ∼10^4 Msun/yr. We also detected eight interacting companion 
 objects close to LBQS 0302-0019\, and confirmed the presence of an obscure
 d AGN at ∼20 kpc of the primary QSO. This work has unveiled with unprece
 dented detail the complex environment of this dual AGN\, which includes ni
 ne interacting companions (five of which were previously unknown). Our res
 ults support a scenario where mergers can trigger dual AGN\, and can be im
 portant drivers for rapid early SMBH growth.
