Dottori 10 ABSTRACT We report –as a part of a long-term study of mergers and IR QSOs– detailed spectroscopic evidences for outflow (OF) and/or Wolf Rayet (WR) features in: (i) low velocity OF ongoing mergers NGC 4038/39 and IRAS 23128-5919; and (ii) extreme velocity OF (EVOF) QSOs IRAS 01003-2238 and IRAS 13218+0552. We also study the presence of OF and EVOF in a complete sample of ultra-luminous IR galaxies/QSOs (“The IRAS 1 Jy MKO-KPNO Survey”, of 118 objects). We found EVOF in IRAS 11119+3257, 14394+5332, 15130+1958 and 15462-0450 (and probable OF in IRAS 05024-1941, 13305-1739, 13451+1232, and 23389+0300). The OF components detected in these objects were mainly associated to starburst processes: i.e., to galactic–winds generated in multiple type II SN explosions and massive stars. The EVOF were detected in objects with strong starburst plus obscured IR QSOs; which suggest that interaction of both processes could generate EVOF. In addition, we analyze the presence of Wolf Rayet features in the large sample of Bright PG- QSOs (Boroson and Green 1992), and nearby mergers and galactic-wind galaxies. We found clear WR features in the Fe II PG-QSOs (type I): PG 1244+026, 1444+407, 1448+273, 1535+547; and in the IR merger Arp 220. We describe the properties of the [O III]λ5007-4959 emission, in strong and extreme Fe II+IR+BAL emitters (QSOs of types I and II). HST archive images of IR+BAL QSOs show in practically all of these objects “arc or shell” features probably associated to galactic-winds (i.e., to multiple type II SN explosions) and/or merger processes. Finally, we discuss the presence of extreme starburst and galactic wind as a possible evolutive link between IR merger and IR QSOs; where the relation between mergers and extreme starburst (with powerful galactic–winds and “multiple” type II SN explosions) plays an important role, in the evolution of galaxies/QSOs.
