Can photo-ionization explain the decreasing fraction of X-ray obscured AGN with luminosity?

A. Akylas, I. Georgantopoulos

Chandra and XMM surveys show that the fraction of obscured AGN decreases rapidly with increasing luminosity. Although this is usually explained by assuming that the covering factor…
