Abstract (from CDS):

We report the discovery of the first hyperluminous infrared galaxy (HyLIG) in the course of the European Large Area ISO Survey (ELAIS). This object has been detected by ISO at 6.7, 15 and 90µm, and is found to be a broad-line, radio-quiet quasar at a redshift z=1.099. From a detailed multicomponent model fit of the spectral energy distribution, we derive a total IR luminosity LIR (1-1000µm)~1.0×10^13h^-2_65 L_☉ (q_0=0.5), and discuss the possible existence of a starburst contributing to the far-IR output. Observations to date present no evidence for lens magnification. This galaxy is one of the very few HyLIGs with a X-ray detection. On the basis of its soft X-ray properties, we suggest that this broad-line object may be the face-on analogue of narrow-line, Seyfert-like HyLIGs.
