Poster Presentation

On the accretion efficiency of type 1 quasars

Author(s): Ruancun Li

Presenter: Ruancun Li (Peking university)

We perform a spectral analysis of a sample of 65 low redshift (z <0.5) quasars. Our sample all have X-ray spectra from XMM–Newton. We fit an energy-conserving, three component accretion model of the broad-band spectral energy distribution (SED) to our multi-wavelength data, allowing us to constrain their bolometric luminosity from these models and estimate their mass accretion rates. Based on our limited sample, we suggest that estimating bolometric luminosities from L5100 °A and L2-10 keV may be unreliable, as has been also noted for a low-redshift, X-ray selected active galactic nucleus sample
