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 ... -
Wide-field Infrared Polarimetry of the ρ Ophiuchi Cloud Core
Kwon, J.; Tamura, M.; Hough, J.~H.; Nakajima, Y.; Nishiyama, S.; Kusakabe, N.; Nagata, T.; Kandori, R. (2015-09-21)We conducted wide and deep simultaneous JHKs-band imaging polarimetry of the ρ Ophiuchi cloud complex. Aperture polarimetry in the JHKs band was conducted for 2136 sources in all three bands, of which 322 sources have ...
