Scientific paper

We propose a long (150 ks) XMM-Newton observation of the Seyfert 1 galaxy NGC7469, to be carried out simultaneously with FUSE UV spectroscopy. We will investigate the connection between the X-ray and UV warm absorber/emitters in this object. A short XMM-Newton observation showed that at least one of the multiple phases of the X-ray warm absorber can be identified with a UV absorber phase. A fuller understanding of this system can only be achieved with a better signal-to-noise RGS spectrum. By understanding the ionisation and velocity structure of the outflow, we can determine its mass and kinetic luminosity, which are necessary for understanding the influence of outflows on the evolution of AGN, their host galaxies, and the surrounding intergalactic medium.
