Suzaku observations of two hard X-ray (> 10 keV) selected nearby Seyfert 2 galaxies are presented. Both sources were clearly detected with the pin Hard X-ray Detector up to several tens of keV, allowing for a fairly good characterization of the broad-band X-ray continuum. Both sources are heavily obscured, one of which (NGC 5728) being Compton thick, while at lower energies the shape and intensity of the scattered/reflected continuum is very different. Strong iron K alpha lines are detected in both sources. There are also hints for the presence of a broad relativistic iron line in NGC 4992.

Abstract
Suzaku observations of two hard X-ray (> 10 keV) selected nearby Seyfert 2 galaxies are presented. Both sources were clearly detected with the pin Hard X-ray Detector up to several tens of keV, allowing for a fairly good characterization of the broad-band X-ray continuum. Both sources are heavily obscured, one of which (NGC 5728) being Compton thick, while at lower energies the shape and intensity of the scattered/reflected continuum is very different. Strong iron K alpha lines are detected in both sources. There are also hints for the presence of a broad relativistic iron line in NGC 4992.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
