NGC1365

Abstract

NGC 1365 is a Seyfert 1.8 galaxy with a rich spectrum of narrow emission and absorption lines. It shows the most robust evidence for four Fe XXV/Fe XXVI K-alpha/K-beta absorption lines from a highly ionised outflow. It shows variable obscuration on timescales as short as days, and relativistically broadened iron line. As it is highly variable down to timescales of hours, it is an ideal target for timing analysis with the Xtend+Resolve instruments. It is also a beautiful example of a luminous AGN in a highly star-forming galaxy, providing an opportunity to probe the AGN-starburst connection. With Resolve, we will, for the first time, robustly measure P Cygni profiles from an ionised wind in an AGN to make an independent estimate of the radius, therefore constraining the launching mechanism.
