    • Magnetic field configuration at the galactic center investigated by wide field near-infrared polarimetry 

      Nishiyama, S.; Tamura, M.; Hatano, H.; Kanai, S.; Kurita, M.; Sato, S.; Matsunaga, N.; Nagata, T.; Nagayama, T.; Kandori, R.; Nakajima, Y.; Kusakabe, N.; Sato, Y.; Hough, J.; Sugitani, K.; Okuda, H. (2009)

    • Magnetic field configuration at the galactic center investigated by wide-field near-infrared polarimetry : transition from a toroidal to a poloidal magnetic field 

      Nishiyama, S.; Hatano, H.; Tamura, M.; Matsunaga, N.; Yoshikawa, T.; Suenaga, T.; Hough, J.; Sugitani, K.; Nagayama, T.; Kato, D.; Nagata, T. (2010)
      We present a large-scale view of the magnetic field (MF) in the central 2° × 2° region of our Galaxy. The polarization of point sources has been measured in the J, H, and KS bands using the near-infrared polarimetric camera ...

A.; Heyrovský, D.; Kandori, R.; Kerins, E.; Lucas, P.W.; Minniti, D.; Nagayama, T.; Rejkuba, M.; Robin, A.C.; Saito, And R. (2014-04-20)
      We present the first microlensing candidate for a free-floating exoplanet-exomoon system, MOA-2011-BLG-262, with a primary lens mass of M host ∼ 4 Jupiter masses hosting a sub-Earth mass moon. The argument for an exomoon ...
