Compton-thick AGN are believed to represent a significant fraction of the cosmicX-ray background especially around 30 keV. However there is a discrepancy inthe fraction obtained from population synthesis models and the observedfraction mainly due to the bias against detecting heavily obscured AGN. Toaddress this we have developed a volume-limited sample of AGN detected by BAT.We select three sources that have soft X-ray data indicative of a Compton-thickscenario. We propose to jointly observe the three sources with NuSTAR andXMM-Newton to confirm their Compton-thick nature and constrain torus propertieswith physically motivated torus models. Doing so will allow us to accuratelymeasure the C-thick AGN fraction in the local Universe after accounting for selection effects. [truncated! Please see actual data for full text]
