Discovery of two bright $z\sim5$ quasars with SkyMapper, Pan-STARRS1 and
  WISE
  We present a search for bright $z\sim5$ quasars using imaging data from
SkyMapper Southern Survey, Pan-STARRS1 and the Wide-field Infrared Survey
Explorer (WISE). We select two sets of candidates using WISE with optical bands
from SkyMapper and alternatively from Pan-STARRS1, limited to a magnitude of
$i<18.2$. We follow up several candidates with spectroscopy and find that the
four candidates common to both lists are quasars, while others turned out to be
cool stars. Two of the four quasars, SMSS J013539.27-212628.4 at $z=4.86$ and
SMSS J093032.58-221207.7 at $z=4.94$, are new discoveries and ranked among the
dozen brightest known $z>4.5$ QSOs in the $i$-band.
