Massive galaxies formed most actively at redshifts $z=1-3$ during the periodknown as `cosmic noon.' Here we present an emission-line study of an extremelyred quasar SDSSJ165202.64+172852.3 host galaxy at $z=2.94$, based onobservations with the Near Infrared Spectrograph (NIRSpec) integral field unit(IFU) on board JWST. We use standard emission-line diagnostic ratios to map thesources of gas ionization across the host and a swarm of companion galaxies.The quasar dominates the photoionization, but we also discover shock-excitedregions orthogonal to the ionization cone and the quasar-driven outflow. Theseshocks could be merger-induced or -- more likely, given the presence of apowerful galactic-scale quasar outflow -- these are signatures of wide-angleoutflows that can reach parts of the galaxy that are not directly illuminatedby the quasar. Finally, the kinematically narrow emission associated with thehost galaxy presents as a collection of 1 kpc-scale clumps forming stars at arate of at least 200 $M_{\odot}$ yr$^{-1}$. The ISM within these clumps showshigh electron densities, reaching up to 3,000 cm$^{-3}$ with metallicitiesranging from half to a third solar with a positive metallicity gradient and Vband extinctions up to 3 magnitudes. The star formation conditions are far moreextreme in these regions than in local star-forming galaxies but consistentwith that of massive galaxies at cosmic noon. JWST observations reveal anarchetypical rapidly forming massive galaxy undergoing a merger, a clumpystarburst, an episode of obscured near-Eddington quasar activity, and anextremely powerful quasar outflow simultaneously.
