Abstract:
We propose a survey of 7 highly obscured Active Galactic Nuclei (logNh>23) to find or set limits at the 10% level on their extended hard (2-7 keV) continuum and Fe-K emission. The Chandra discovery that 10-30% of the 2-7 keV continuum from high Nh AGN can be extended on scales from ~100 pc up to ~2 kpc affects the structure of the obscuring torus determined from NuSTAR spectra, and demonstrates the AGN impact on the host galaxy, i.e. AGN feedback. By completing a sample of 20 BASS high Nh AGN we can look for predictors of hard extent; their feedback duty cycle may also be estimated on ~1000 year timescales.
