Scientific paper

X-ray data with high-resolution in the spatial and energy domains are crucial to derive the geometrical distribution and the physical properties of gas and dust surrounding Active Galactic Nuclei (AGN). We present in this paper CIELO-AGN, the first catalogue of ionised emission lines detected in the soft X-ray spectra of a sample of 69 nearby obscured AGN. This catalogue has been implemented according to an IVOA Data Model, and can be accessed through VO-compatible applications. The results extracted from CIELO support the scenario, whereby the active nucleus is responsible for the X-ray ``soft excess'' almost ubiquitously observed in nearby obscured AGN via photoionization of circumnuclear gas.
