Black hole accretion and outflows at z ∼ 2

QSOs at z similar to 2 - 3 become relic black holes in the nuclei of nearby galaxies. Using new near infraxed spectroscopy we determine eimission-line strengths of Hbeta, optical Fe II and [O III]lambda5007, and FWHM Hbeta Thus we derive black hole masses and Eddington accretion ratios and compaxe these with emission-line indicators of black-hole fueling. All of our bright, high-z QSOs axe inevitably biased towards high black-hole mass and high Eddington ratio. We show that the Boroson & Green inverse relationship between Fe II (optical) and [O III] strengths extends to z - 2 and depends on Eddington ratio rather than black-hole mass. The BALQSOs have stronger Fe II and weaker [O III] than non-BALQSOs, indicating a more plentiful fuel supply for similar Eddington ratio. We have observed the brighter SDSS BALQSOs in this investigation, and SDSS is providing many BALQSOs with a wide range of BAL chaxacteristics needed for further such investigations.
