Abstract:
The "Cosmic Evolution Survey" (COSMOS) enables the study of the
spectral energy distributions (SEDs) of active galactic nuclei (AGNs)
because of the deep coverage and rich sampling of frequencies from
X-ray to radio. Here we present an SED catalog of 413 X-ray
(XMM-Newton)-selected type 1 (emission line FWHM>2000km/s) AGNs with
Magellan, SDSS, or VLT spectrum. The SEDs are corrected for Galactic
extinction, broad emission line contributions, constrained
variability, and host galaxy contribution. We present the mean SED and
the dispersion SEDs after the above corrections in the rest-frame
1.4GHz to 40keV, and show examples of the variety of SEDs encountered.
In the near-infrared to optical (rest frame ∼8µm-4000Å), the
photometry is complete for the whole sample and the mean SED is
derived from detections only. Reddening and host galaxy contamination
could account for a large fraction of the observed SED variety.
