Properties of Very Broad Line MgII Radio-Loud and Radio-Quiet Quasars
  We perform an analysis of the properties of radio-loud (RL) and radio-quiet
(RQ) quasars with MgII broad emission line (i-band magnitude $\leq 19.1$ and z
$\leq 1.9$), selected from the parent sample of SDSS DR7 catalogue. For sources
with full-width half maxima (FWHM) greater than \mbox{15,000 km s$^{-1}$} (very
broad line sample; VBL) we find the radio loud fraction (RLF) to be about 40\%.
To further investigate this result we compare the bolometric luminosity,
optical continuum luminosity, black hole (BH) mass and Eddington ratios of our
VBL sample of RL and RQ quasars. Our analysis shows that in our VBL sample
space, RL quasars have higher luminosities and BH mass than RQ quasars. The
similarity in the distribution of their covering fraction (CF) shows that there
is no difference in dust distribution between VBL RL and RQ quasars and hence
dust is not affecting our results. We also find that there is no correlation of
RL quasar properties with optical continuum luminosity and BH mass.
