This has been done efficiently in the past using 2XMM and IRAS data (Severgnini et al. 2012). In this talk I will present my thesis work in which I tested this technique using the latest 3XMM and WISE data for the sample presented by Severgnini et al. I will also briefly discuss the X-ray spectral properties of all of those sources showing flux and/or spectral variability in the XMM-Newton observations.ELETTRONICOenMultimedia10.5281/zenodo.163800https://zenodo.org/record/163800#.Xp8s5K3W4ht2016agnt.confE..43ZFIS/05 - ASTRONOMIA E ASTROFISICA
