Chandra and XMM monitoring of NGC 1365: unveiling the structure of the compact circumnuclear absorber
Guido Risaliti (SAO)
I present the results of a Chandra monitoring of the Seyfert Galaxy NGC 1365, which revealed an occultation event with a duration of less than two days, implying a distance of the circumnuclear absorber of less than 0.01 pc, and a size of the X-ray emitting region of 10^14 cm. I will discuss the implication of this result in the context of the unified model, and will present the first results of a long ( 5 days) XMM monitoring of this source.
