Tracking Down the Ionized Outflow of NGC 7469

Using a multiwavelength campaign on NGC 7469, led by XMMNewton, HST, Swift,NuSTAR, and optical, we propose to achieve new physical insights into theenigmatic AGN winds, by obtaining the deepest ever RGS spectrum of this highlyaccreting source. It will allow us to determine the accurate ionisation andchemical structure of the wind. Using EPIC and RGS, we will measure the responseof the outflow to continuum variations, which combined with HST/COS data willunambiguously determine the location, and abundances of the outflow components.Our team pioneered this approach, and applied it successfully (14 refereedpapers) to Mrk 509 that featured only a multiyear response. The uniqueproperties of NGC 7469 make it the ideal candidate to respond on shorter, bettermonitored time scales. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
