Abstract
Active Galactic Nuclei emit over the entire electromagnetic spectrum with the peak of the accretion disk emission in the far‐UV, a wavelength range historically difficult to investigate. We use here the GALEX (Galaxy Evolution Explorer) Near‐UV and Far‐UV measurements (complemented with optical data from Sloan Digital Sky Survey (SDSS) and XMM‐Newton X‐ray spectra) of a sample of 83 X‐ray selected type 1 AGN extracted from the XMM‐Newton Bright Serendipitous Survey (XBS) to study their spectral energy distribution (SED) in the optical, Near and Far‐UV and X‐ray energy bands. We have constrained the luminosity of the accretion disk emission component and calculated the hard X‐ray bolometric corrections for a significant sample of AGN spanning a large range in properties (z, Lx).
