Outflow variability and black hole occultation in NGC 1365

We propose a 360 ksec observation of the Seyfert Galaxy NGC 1365, a sourcehaving a unique set of properties, which make it the best suited target amongXray absorbed AGNs to study the innermost region of AGNs: FeXXV and FeXXVIKalpha and Kbeta absorption lines (the highest S/N detection so far among AGNs),rapidly varying cold absorber (N_H variations of virgul10^{23}cm^{2} in a few hours,changes from Comptonthick to Comptonthin in two days), a relativistic ironemission line. This new long observation will constrain the dimensions of theabsorbers, and, for the first time, allow the investigation of the dynamics andphysical conditions of the hot absorber responsible of the iron absorptionlines. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
