An irradiated accretion disc in the narrow-line Seyfert 1 RE J1034+396?

We model the optical to X-ray continuum spectrum of the narrow-line Seyfert 1 galaxy RE J1034+396. We show that the flat optical spectrum is consistent with emission from an irradiated accretion disc. The X-ray emission can be modelled with a disc blackbody and a Comptonized component. The temperature at the inner edge of the disc T-in = (0.12 +/- 0.02) keV. Using this constraint, we show that the flat optical spectrum is consistent with emission from the irradiatively heated outer part of the accretion disc. We constrain the outer radius of the optically thick disc (R greater than or similar to 5 x 10(16) cm) and the inner radius of the irradiation-dominated region (R greater than or similar to 5 x 10(12) cm). Our optical and X-ray spectral fits indicate a mass 0.6 less than or similar to M less than or similar to 3 x 10(6) M., and do not rule out a low (i.e. face-on) inclination angle for the and do not rule out a low (i.e. face on) system.
