A Chain of Dark Clouds in Projection Against the Galactic Center
Takahiro Nagayama, Shuji Sato, Shogo Nishiyama +9
In the J, H, and Ks bands survey of the the Galactic Center region over an area of 2deg x 5deg, we have found many dark clouds, among which a distinguished chain of dark clouds can…
Near-Infrared Polarimetry toward the Galactic Center
Shogo Nishiyama, Motohide Tamura, Hirofumi Hatano +4
Near-infrared polarimetry of point sources reveals the presence of a toroidal magnetic field in the central 20' x 20' region of our Galaxy. Comparing the Stokes parameters between…
Magnetic Field Configuration at the Galactic Center Investigated by Wide Field Near-Infrared Polarimetry
Shogo Nishiyama, Motohide Tamura, Hirofumi Hatano +13
We present a polarimetric map of a 20'x20' area toward the Galactic center. The polarization of point sources has been measured in the J, H, and Ks bands using the near-infrared po…
Interstellar Extinction Law toward the Galactic Center II: V, J, H, and Ks Bands
Shogo Nishiyama, Tetsuya Nagata, Motohide Tamura +4
We have determined the ratios of total to selective extinction directly from observations in the optical V band and near-infrared J band toward the Galactic center. The OGLE (Optic…
Herbig Ae/Be Stars in the Magellanic Bridge
Shogo Nishiyama, Yasuaki Haba, Daisuke Kato +11
We have found Herbig Ae/Be star candidates in the western region of the Magellanic Bridge. Using the near infrared camera SIRIUS and the 1.4 m telescope IRSF, we surveyed about 3.0…
