Query: Near-Infrared Polarimetric Study of N159/N160 Star-Forming Complex in
  the Large Magellanic Cloud   We present near-infrared polarimetric results for N159/N160 star-forming
complex, in the Large Magellanic Cloud (LMC) with SIRPOL, the polarimeter of
the Infrared Survey Facility (IRSF). We separated foreground sources using
their visual extinction derived from near-infrared photometric data. The 45
young stellar candidates and 2 high excitation blobs were matched with our
sources, and 12 of them showed the high polarization that was not originated
from the interstellar dust. We made a polarimetric catalog of 252, 277, and 89
sources at $J$, $H$, and $K_s$ bands, respectively. Based on the ratios of
polarization degree among these bands, we verify that the origin of these
polarized sources is the dichroic extinction from the aligned interstellar dust
by magnetic field and that the ratios follow a power-law dependence of
$P_{\lambda}$ $\sim$ $\lambda^{-0.9}$. The linear polarization vectors
projected on the H$\alpha$ image of the complex turned out to follow local
magnetic field structure. The vector map overlaid on dust and gas emissions
shows the close correlation between magnetic field structure and surrounding
interstellar medium. We suggest that the derived magnetic field structure
supports the sequential formation scenario of the complex.
