Title: UV to Mid-IR SEDs of Low Redshift Quasars
Authors: Zhaohui Shang
Topic: 1 
Session: oral 

Abstract: UV to infrared spectral energy distributions (SED) of quasars are
important to understand the accretion of black holes and their
surrounding environment, as well as quasar total energy output.  We
will present UV (some far-UV), optical and Spitzer mid-IR spectra for
a sample of low-redshift quasars (z<0.4), compare their properties in
different wavelength bands, especially between the UV and mid-IR.  We
will also discuss the possibility of a better way to estimate quasar
bolometric luminosity, which is critical for obtaining Eddington
accretion ratio.
