Description
Some of the fundamental properties inferred for quasar accretion disks remain in apparent tension with theoretical predictions. I will show that much of the discrepancy concerning accretion-disk sizes and their emitted spectrum can be traced to a previously poorly constrained and under-appreciated contribution from diffuse, non-disk emission. Accounting for this component systematically alters how reverberation-mapping and microlensing measurements are interpreted, and substantially reduces the inferred tension between observed disk sizes and spectra and standard accretion-disk models.
