Keck spectroscopy XMM-PV type II AGN GAL (log L X =40.2, soft source) type II AGN (log L X ~43.0) type II/Gal (log L X ~42.0)
Type II AGNs vs. Galaxies High ionization narrow emission lines (e.g, Ne V) Hydrogen column density log N H > >Intrinsic absorption X-ray luminosity log L X > 43.0 Narrow emission lines (no NeV) or galaxy- like spectra Hydrogen column density log N H ~ 20.0 No intrinsic absorpt. X-ray luminosity log L X < 42.0

Spectroscopic follow-up of the 700ksec sample …on going with 4 masks in March ………some new-z from Ingo…
RX J high-z cluster XMM EPIC Chandra HRC Hashimoto et al., 2003New redshift! Optically confirmed
Summary Flux limit in the [5-10 keV] lower than in 1Msec Chandra surveys ->highly absorbed sources High quality X-ray spectra High identification completeness for the hard sample On going Keck spectroscopy on the newly detected X-ray sources
