PHIBSS: molecular gas, extinction, star formation and kinematics in the
  z=1.5 star forming galaxy EGS13011166
  We report matched resolution, imaging spectroscopy of the CO J=3-2 line (with
the IRAM Plateau de Bure millimeter interferometer) and of the H-alpha line
(with LUCI at the Large Binocular Telescope)in the massive z=1.53 main-sequence
galaxy EGS 13011166, as part of the "Plateau de Bure high-z, blue sequence
survey (PHIBSS). We combine these data with HST V-J-J-H-band maps to derive
spatially resolved distributions of stellar surface density, star formation
rate, molecular gas surface density, optical extinction and gas kinematics. The
spatial distribution and kinematics of the ionized and molecular gas are
remarkably similar and are well modeled by a turbulent, globally Toomre
unstable rotating disk. The stellar surface density distribution is smoother
than the clumpy rest-frame UV/optical light distribution, and peaks in an
obscured, star forming massive bulge near the dynamical center. The molecular
gas surface density and the effective optical screen extinction track each
other and are well modeled by a 'mixed' extinction model. The inferred slope of
the spatially resolved molecular gas to star formation rate relation depends
strongly on the adopted extinction model and can vary from 0.8 to 1.7. For the
preferred mixed dust-gas model we find a near linear slope.
