What about Compton-thick AGN?

• Fraction 20-40%, L-indep (AGN)
• Galaxy-scale gas: 0% (GRB)
• Must be nuclear (“torus” or CMZ)
• Compton-thin sky obscured by host galaxy
• Random orientations:
• Compton-thin obscured fraction AGN – gal obscuration
• Poles aligned:
• Gal obscuration lower
• Torus pole always points to disk
• Gal obscuration higher
