Descripción
New results of a program to study BAL + IR + FeII QSOs, using Gemini/GMOS-IFU spectroscopy and HST data, are presented for IRAS 17002+5153 and IRAS 07598+6508. In particular, the Gemini GMOS-IFU data show that: (i) IRAS 17002+5153: the 3D spectra in the region of the shells (at radius of 1.3") show multiple emission line components (with Δ V~280--500 km/s), with typical properties of Liners associated with low velocity shocks. (ii) IRAS 07598+6508: the 3D spectra in the circumnuclear area where a possible shell (at r of 2.3") show multiple emission line components also with typical properties of Liners associated with shocks. These results confirm our previous suggestion that: these two similar BAL QSOs could be considered as exploding BAL + IR + FeII QSOs (which are also very similar to the exploding QSOs Mrk 231 and IRAS 04505-2958). Thus, these new Gemini GMOS data are in good agreement with our extreme outflow + explosive + evolutionary model for QSOs and galaxy formation and evolution.
