The Fe-K band shows sometimes relativistic absorption lines, so called ultrafast outflows. The geometrical structure, ionisation structure, location, origin and actual driver of these absorbers are still under debate. We detect them by a powerful technique described in Tombesi et al 2010 and then identify them. We detected He-like and H-Like transitions of FeXXV and FeXXVI, respectively, in the 6.4-9 keV band. These Fe-K absorbers are found to have outflow velocity in the 1500- 5000 km/s range. The absorption lines strengthen with the 4-10 keV flux of the powerlaw continuum. We found that the continuum slope is also highly variable (Γ ~ 1 - 2.1) in the 4-10 keV band. We will discuss the response of absorbers to the changes in the continuum spectral components. |
