The XMM-Newton view of PG quasars: II. Properties of the Fe K-alpha line

E. Jimenez-Bailon, E. Piconcelli, M. Guainazzi +3

The properties of the fluorescence Fe K-alpha emission lines of a sample of 38 quasars (QSOs) observed with XMM-Newton are studied. These objects are included in the optically sele…

Transmission- to reflection-dominated transition in Seyfert 2 galaxies: the XMM-Newton view

M. Guainazzi, P. Rodriguez-Pascual, A. C. Fabian +3

In this paper we present the current status of a XMM-Newton program to observe an optically-defined, complete and unbiased sample of Compton-thick Seyfert 2 galaxies. The main goal…
