Oral title: Testing orientation effects with heavily obscured AGN and NuSTAR Oral abstract: With its unprecedented sensitivity above 10 keV, NuSTAR has revolutionized the study of the most heavily obscured AGN. Combined with spectral models to correctly account for the reprocessing effects, we have measured the intrinsic accretion parameters in the X-rays, being the luminosity and power-law index to highest accuracy yet in these systems. Comparing to well-studied unobscured systems, this has allowed us to study orientation effects and test the AGN unified scheme as never been done before.
