Issue Date: | 2017 | Volume: | The X-ray Universe 2017 | First Page: | 341 | Abstract: | An efficient diagnostic method to find local (z<0.1) Compton-thick AGN consists in selecting sources characterized by hard X-ray colors and low X-ray to mid-IR flux ratio (HR vs. F_{X}/F_{IR}). This has been done efficiently in the past using 2XMM and IRAS data (Severgnini et al. 2012). I will here summarize my master thesis work, in which I tested the stability of the method outlined above using the latest 3XMM and WISE data, and I investigated its potentialities in finding interesting spectrally variable (including changing-look) XMM-Newton sources. | Conference Name: | The X-ray Universe 2017 | Conference Place: | Roma | Conference Date: | 6-9 June, 2017 | URI: | http://hdl.handle.net/20.500.12386/27040 | URL: | https://www.cosmos.esa.int/web/xmm-newton/2017-symposium | Bibcode ADS: | 2017xru..conf..341Z | Fulltext: | open |
