A Quasar-Galaxy Mixing Diagram: Quasar Spectral Energy Distribution Shapes in the Optical to Near-Infrared
Heng Hao, Martin Elvis, Angela Bongiorno +19
We define a quasar-galaxy mixing diagram using the slopes of their spectral energy distributions (SEDs) from 1μm to 3000Å and from 1μm to 3μm in the rest frame. The mixing diagram…

Spectral Energy Distributions of Type 1 AGN in XMM-COSMOS Survey II - Shape Evolution
Heng Hao, Martin Elvis, Francesca Civano +18
The mid-infrared to ultraviolet (0.1 -- 10 ) spectral energy distribution (SED) shapes of 407 X-ray-selected radio-quiet type 1 AGN in the wide-field ``Cosmic Evolution Survey"…
