Abstract
We have performed several simulations in order to test the scientific capabilities of the IXO calorimeter, with particular emphasis on the detection of absorption lines in the 3-11keV band. We derived the flux limits for their detection on several time-scales, compared different response matrices available and simulated realistic spectra from photo-ionized warm absorbers in AGNs. This study illustrates the considerable improvements that this instrument will bring to high resolution spectroscopy, especially related to the study of accretion and outflows in the central regions of AGNs.
