The Extreme Ultraviolet Spectrum of the Kinetically Dominated Quasar 3C
  270.1
  Only a handful of quasars have been identified as kinetically dominated,
their long term time averaged jet power, $\overline{Q}$, exceeds the bolometric
thermal emission, $L_{bol}$, associated with the accretion flow. This letter
presents the first extreme ultraviolet (EUV) spectrum of a kinetically
dominated quasar, 3C 270.1. The EUV continuum flux density of 3C 270.1 is very
steep, $F_{\nu} \sim \nu^{-\alpha_{EUV}}$, $\alpha_{EUV} =2.98\pm 0.15$. This
value is consistent with the correlation of $\overline{Q}/L_{bol}$ and
$\alpha_{EUV}$ found in previous studies of the EUV continuum of quasars, the
EUV deficit of radio loud quasars. Curiously, although ultraviolet broad
absorption line (BAL) troughs in quasar spectra are anti-correlated with
$\overline{Q}$, 3C 270.1 has been considered a BAL quasar based on an SDSS
spectrum. This claim is examined in terms of the EUV spectrum of OVI 1and the
highest resolution CIV spectrum in the archival data and the SDSS spectrum.
First, from [OIII]4959,5007 (IR) observations and the UV spectral lines, it is
concluded that the correct redshift for 3C 270.1 is 1.5266. It is then found
that the standard measure of broad absorption, BALnicity = 0, for MgII 2800,
CIV 1549 and OVI 1032 in all epochs.
