"Probing the Brightest QSOs though the Spatial Distribution of Galaxies and (Fluorescent) Lya Emitters" (host: Karl Gebhardt)
QSOs are ubiquitous in the high-redshift universe, but the most luminous QSOs (L ~ 10^14 Lsun) are extremely rare even at the peak redshifts of black hole growth, 2 < z < 3. I will present detailed probes of such hyperluminous QSOs and their environments at these redshifts using deep surveys of 1558 continuum-selected galaxies (LBGs; R < 25.5) and 890 Lya-emitters (LAEs; NB_Lya < 26.5) selected to lie in the neighborhoods (or foreground/background) of the QSOs. Using clustering statistics, we derive the halo masses of the QSOs and LBGs and place their central black holes on the M_DM-M_BH relationship, finding a large discrepancy compared to the estimates at low redshift. Using the sample of LAEs, we present evidence for a fluorescent contribution to their Lya emission, and we constrain the lifetime and opening angle of QSO emission via the 3D distribution of fluorescent Lya emitters. Finally, I will discuss prospects for further study of the QSOs and the Lya-emitting gas and galaxies via NIR spectroscopy and applications to future Lya surveys.
