AbstractWe present a study of a sample of SDSS-dr10 galaxies with significant [OIII]5007A emission lines (a good proxy for nuclear activity and/or star formation) in fields included in the 3XMMe catalogue. Using the tools and techniques of the ARCHES project we cross-correlated the SDSS-dr10 (optical), the 3XMMe (X-rays) and the WISE All-Sky (MIR) catalogues. We assembled a sample of 2235 [OIII]5007A emitting galaxies with multiwavelength data. In a first view of the properties of these sources we found 954 galaxies showing some evidence of an AGN in some energy range. However, only for 425 sources (~45%) the AGN is detected in all ranges (optical, MIR and X-rays). We can therefore test the eficiency of AGN detection in different energy ranges and through an extensive multiwavelength study we can understand why the AGN is not detected (optical or X-ray obscuration, low luminosity, galaxy dilution, etc).
