  Forward di-jet production in d+Au collisions at RHIC provides sensitivity to
Bjorken-x between 0.001 and 0.02 for the nuclear gluon density . The STAR
experiment at RHIC has continuous azimuthal coverage with electromagnetic
calorimeters for pseudo-rapidity from -1 to 4. We have measured
forward+mid-rapidity $\pi^{0}-\pi^{0}$ and $\pi^{0}-h$ azimuthal correlations
and forward+forward rapidity $\pi^{0}-\pi^{0}$ azimuthal correlations. Both
analyses use the Forward Meson Spectrometer (FMS) triggered data in RHIC 2008
run p+p and d+Au collisions at $\sqrt{s_{NN}}$=200 GeV. The end-cap
electromagnetic calorimeter (EEMC) at STAR covers pseudo-rapidity from 1.07 to
2. This provides us sensitivity to the nuclear gluon density at intermediate x
values. Preliminary results on the $\pi^{0}-\pi^{0}$ and $\pi^{0}$ + jet-like
azimuthal correlations with both the FMS and the EEMC will be discussed.
