type II AGN

type II AGN (log LX~43.0)

type II/Gal (log LX~42.0)

Page 17: New XMM-Newton     deep Survey in the Lockman Hole

Type II AGNs vs. Galaxies

• High ionization narrow emission lines (e.g, Ne V)

• Hydrogen column density log NH > 22.0->Intrinsic absorption

• X-ray luminosity log LX > 43.0

• Narrow emission lines (no NeV) or galaxy-like spectra

• Hydrogen column

density log NH~ 20.0

No intrinsic absorpt.

• X-ray luminosity log LX< 42.0

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
