Discovery of a lensed ultrabright submillimeter galaxy at z=2.0439
  We report an ultra-bright lensed submillimeter galaxy (SMG) at $z=2.0439$,
{\it WISE} J132934.18+224327.3, identified as a result of a full-sky
cross-correlation of the {\it AllWISE} and {\it Planck} compact source catalogs
aimed to search for bright analogs of the submillimeter galaxy SMMJ2135, the
Cosmic Eyelash. Inspection of archival SCUBA-2 observations of the candidates
revealed a source with fluxes (S$_{850 \mu m}$= 130 mJy) consistent with the
{\it Planck} measurements. The centroid of the SCUBA-2 source coincides within
1 arcsec with the position of the {\it AllWISE} mid-IR source, and, remarkably,
with an arc shaped lensed galaxy in {\it HST} images at visible wavelengths.
Low-resolution rest-frame UV-optical spectroscopy of this lensed galaxy
obtained with 10.4 m GTC reveals the typical absorption lines of a starburst
galaxy. Gemini-N near-IR spectroscopy provided a clear detection of
H$_{\alpha}$ emission. The lensed source appears to be gravitationally
magnified by a massive foreground galaxy cluster lens at $z = 0.44$, modeling
with Lenstool indicates a lensing amplification factor of $11\pm 2$. We
determine an intrinsic rest-frame 8-1000-$\mu$m luminosity, $L_{\rm IR}$, of
$(1.3 \pm 0.1) \times 10^{13}$ $L_\sun$, and a likely star-formation rate (SFR)
of $\sim 500-2000$ $M_\sun yr^{-1}$. The SED shows a remarkable similarity with
the Cosmic Eyelash from optical-mid/IR to sub-millimeter/radio, albeit at
higher fluxes.
