Hyper-luminous Reddened Broad-Line Quasars at z~2 from the VISTA
  Hemisphere Survey and WISE All Sky Survey
  We present the first sample of spectroscopically confirmed heavily reddened
broad-line quasars selected using the new near infra-red VISTA Hemisphere
Survey and WISE All-Sky Survey. Observations of four candidates with (J-K)>2.5
and K<=16.5 over ~180 sq deg, leads to confirmation that two are highly
dust-reddened broad-line Type 1 quasars at z~2. The typical dust extinctions
are AV ~ 2-2.5 mags. We measure black-hole masses of ~10^9 M0 and extinction
corrected bolometric luminosities of ~10^47 erg/s, making these among the
brightest Type 1 quasars currently known. Despite this, these quasars lie well
below the detection limits of wide-field optical surveys like the SDSS with iAB
> 22. We also present WISE photometry at 3--22um, for our full sample of
spectroscopically confirmed reddened quasars including those selected from the
UKIDSS Large Area Survey (Banerji et al. 2012a). We demonstrate that the
rest-frame infrared SEDs of these reddened quasars are similar to UV-luminous
Type 1 quasars with significant hot dust emission and starburst quasar hosts
like Mrk231. The average 12um flux density of our reddened quasars is similar
to that of the recently discovered HyLIRG WISE1814+3412 (z=2.452) at similar
redshifts, with two of our reddened quasars also having comparable 22um flux
densities to this extreme HyLIRG. These optically faint, heavily reddened
broad-line quasars are therefore among the most mid infrared luminous galaxies
at z~2, now being discovered using WISE.
