Description
Almost twenty years of X-ray grating observations allowed us to characterize the multi-component ionized gas, outflowing from active galactic nuclei, with unprecedented accuracy. XMM-Newton combined with HST have been key in unveiling the secrets of outflowing winds.
Here I will show the results of our most recent multi-wavelength campaign on the narrow line Seyfert 1 IZw1 (230 ks with XMM and 6 orbits of HST time). The simultaneous observation shows a surprising UV-X warm absorber behaviour as well as clearly pointing to a line-driven wind launching mechanism of the plasma (Silva, Costantini et al. 2018). I will show how the observational elements of this and of previous observations clearly challenge the classical view of a conical-shaped outflow in ionization equilibrium. The observational evidences indeed strongly favour episodes of gas ejection, possibly from the accretion disk.
