| Abstract: |
We present an extraordinary variation of the X-ray spectrum of the obscured AGN in NGC 1365, which was observed by Chandra to change from Compton-thin to Compton-thick and back to Compton-thin in four days. This fast variation implies a a size of ~ 1014 cm for the emitting region, and an extremely compact size (~ 1016 cm) for the clumpy circumnuclear absorber. |
