X‐ray vs. H2Omaser emission in AGN

Correlations between X‐ray and water maser emission in AGN have been recently reported. However, the lack of systematic studies affects the confidence level of these results. In the following, we introduce a project aimed at studying all the water maser sources believed to be associated with AGN activity through X‐ray data obtained with the XRT and BAT instruments on‐board the Swift satellite. Preliminary results of this work indicate a promising rate of XRT detections allowing us to refine follow‐up observing strategies focused on investigating the nuclei of individual galaxies and deriving, on statistical basis, the main characteristics of water maser hosts. In addition, a cross‐correlation between our sample and the BAT 22‐months all‐sky survey provides an exceptionally high detection rate at hard X‐ray energies when compared to other AGN‐related catalogs.
