Abstract: The multiwavelength coverage of the COSMOS project, with deep observations at radio, infrared, optical, UV, and X-ray wavelengths, allows for an unparalleled study of the bolometric properties of a variety of AGN. Our sample of spectroscopically confirmed AGN is primarily X-ray selected and is especially sensitive to optically obscured AGN. We couple the multiwavelength spectral energy distributions of our Type 1 and Type 2 AGN along with measurements of their optical emission lines in order to study basic AGN physics. Early results suggest a minimum Eddington ratio for Type 1 AGN.
