Conclusions

• GRB show mass-dependent obscuration
• Relation can predict LOS distribution for individual galaxies
• For AGN population:
• Caveats: SF distribution, metallicity
• Galaxy gas+dust can explain much of the AGN obscuration at NH = 1022 – 1023 cm-2
• For Torus models:
• Covering factors is … (see Buchner et al. in prep)
• Diminished in luminous AGN
