Description

In this talk, I will present a review of the most recent results obtained by the Clemson-INAF CT-AGN collaboration. This project is based on the Palermo Swift-BAT catalog: by taking advantage of Swift-BAT effectiveness in detecting heavily obscured AGN at z~0, our group performed a multi-year, multi X-ray telescope effort aimed at obtaining a complete census of the obscured AGN population in the local Universe, while at the same time characterizing with unprecedented quality the properties of heavily obscured accreting supermassive black holes (SMBHs).
In particular, I will discuss the most recent developments of the project, and how we are working on building a large sample of heavily obscured AGN with multi-epoch X-ray observations, that are needed to characterize the properties of the clumpy medium surrounding accreting SMBHs, as well as to understand the complex feeding-feedback interplay which takes place between the SMBH and its host galaxy.
