obscured fraction-luminosity relation

(relation between AGN luminosity and surrounding dust IR emission)

The phrase obscured fraction-luminosity relation is used for a relation between the mid-infrared emission of an active galactic nucleus (AGN) attributed to black-body radiation from obscuring dust and the portion of X-ray luminosity that is obscured (i.e., the obscured fraction of its luminosity). Efforts have been made to discover such relations and to determine when one or more are applicable.
