Transmission- to Reflection-dominated Transition in Seyfert 2 Galaxies: the XMM-Newton View
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 of this project is the measurement of the occurrence rate of transition between transmission- (i.e. Compton-thin), and reflection-dominated spectral states. These
