ASCA observations of deep ROSAT fields V. The X-ray spectrum of hard X-ray selected QSOs

A. Pappa, G. C. Stewart, I. Georgantopoulos +3

We present an analysis of the \rosat and \asca spectra of 21 broad line AGN (QSOs) with z∼1 detected in the 2-10 keV band with the \asca \gis. The summed spectrum in the \asc…

The X-ray spectra of optically selected Seyfert 2 galaxies. Are there any Sy2 galaxies with no absorption?

A. Pappa, I. Georgantopoulos, G. C. Stewart +1

We present an X-ray spectral analysis of a sample of 8 bona-fide Seyfert 2 galaxies, selected on the basis of their high [OIII]λ5007 flux, from the Ho et al. (1997) spectro…
