Enlarging the parameter space of ionized outflowing absorbers in quasars

We propose a deep (100 ks) spectroscopic followup of a recentlydiscoveredionized absorber with unprecedented physical parameters. The unique combinationof large column density, ionization state and source redshift (zvirgul0.66) makes itthe most massive and the most distant warm absorber detected so far. We designour program to impose meaningful constraints on its kinematics with the aim ofproviding an unambiguous classification of the ionized absorber and extendingthe observed parameter space of nuclear outflows traced by ionized gas in AGN. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
