Rapid Compton-thick/Compton-thin Transitions in the Seyfert 2 Galaxy NGC 1365
We present multiple Chandra and XMM-Newton observations of the type 1.8 Seyfert Galaxy NGC 1365, which shows the most dramatic X-ray spectral changes observed so far in an AGN: the source switched from reflection dominated to transmission dominated and back in just 6 weeks. During this time the soft thermal …
