IRAS13349+2438: a unique laboratory to probe the innermost regions of the accret

We propose to observe the Narrow Line Seyfert 1 galaxy IRASvirgul13349+2438 withXMMNewton for a total exposure of 130virgulks. The main objective of our proposalare 1) the study of the Fe K band which exhibits spectral complexity due to thesimultaneous presence of a broad relativistic Fe line and absorption structures,one of which is significantly redshifted with respect to the expected energy. Wewill use the observation to separate the different spectral components, toconfirm the presence of energyshifted absorption lines, and to study the shorttimescale variability of the absorption features; 2) the study of the warmabsorber and, in particular, of its longterm variations. truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
